An investigation study on pulverized eggshell as a partial replacement of cement for non-load bearing concrete hollow blocks

In order to minimize the problem and develop a useful, practical, and affordable construction material, the researchers discovered the use of waste materials. Because of the scarcity, the researchers are motivated to utilize the solid waste generated by households and companies that use eggs in their production of goods. The researchers propose using Egg Shells to develop an alternative cement for the concrete mixture. The study has three main objectives: (1) to determine the 7-day, 14-day, and 28-day compressive strengths of concrete when pulverized egg shells are used as a partial replacement for cement; (2) to determine the water absorption percentage of the concrete when the pulverized eggshell is used as a partial replacement for cement in concrete; and (3) to perform a cost analysis in the preparation of a concrete mix with pulverized eggshell as compared to the standard concrete mixture. The study involves cost analysis and two tests: compressive strength and water absorption. To achieve the result from the compressive test, the researchers made CHB specimens consisting of nine for each experimental (5%, 10%, and 15% cement partial replacement) setup and nine standard concrete mixtures for each different curing age (7, 14, and 28 days). Based on the analysis of the findings, the researchers conclude that eggshells can be a partial replacement for cement for non-load-bearing concrete hollow blocks. The samples were tested using the Universal Testing Machine (UTM), and the results show that the concrete samples with 10% replacement of PES have higher compressive strength than the standard concrete samples, all of the specimens have passed the ASTM C129 standards in both the compressive strength test and the water absorption test. Also, using pulverized egg shells can reduce the cost of the project. However, only a 10% replacement of eggshell is highly recommended.

PROJECT RESCUER: Response to Community Underlying Earthquake Risks from the Unheeded Discovery of Lubao Fault through Awareness Assessment and Modification of Existing Evacuation Plan

Modification of evacuation systems is sometimes hindered by restrictions that include the lack of information and publicity regarding the new discovery of an environmental concern such as a fault line. The safety and well-being of residents can become significantly affected as a result of these constraints. The main purpose of this research study is to assess the sense of awareness of the local residents in Brgy. Baruya, Lubao, Pampanga towards the discovery of the Lubao Fault and to propose some modifications in their existing evacuation plan. A survey questionnaire was administered to the 357 residents of Barangay Baruya who were extracted through the use of a simple random technique. The results revealed that the focused population stands to disagree that they know the Lubao Fault and its attributes in terms of the highest magnitude and the underlying risks it can produce. Moreover, a structured interview was conducted with the Lubao Disaster and Risk Reduction Management Office (LDRRMO). The summary of transcribed answers indicated that they have an available general evacuation system and do not hold separate evacuation procedures in an earthquake situation. The community of Baruya was not thus far given the particular earthquake preparations that are purposively intended for the potential strike of the Lubao Fault. The Jose Abad Santos Avenue and the Lubao Bypass Road were set to be the routes of evacuation mobility. Available rescue vehicles and the aforementioned road networks were optimized in three cases. Open safe spaces and danger zones during earthquakes were identified through community evaluation and utilization of the HazardHunterPH tool. The proposed safety signages were provided with specifications. Overall, the areas covered by the modification in this present study are all open for integration into the future earthquake evacuation plan of Lubao, Pampanga.

Flood mitigation system: Proposed permeable concrete road and drainage on Parian, Mexico Pampanga

When water overflows onto normally dry ground, flooding occurs. Heavy rains, clogged drainage systems, and occasionally failed levees or dams can all result in flooding. This study was conducted to calculate the maximum load-bearing capacity of the permeable concrete used in the road and drainage system and to test the infiltration rate of the permeable concrete. To identify the major issue of water stagnation and to provide a solution, a thorough investigation was conducted in the area, focusing on the Barangay Parian Mexico, Pampanga. In order to support the study and determine the appropriate mixture ratio for permeable concrete, data were gathered and analyzed. Following the data collection, a mixture with a 1:3:0 ratio of cement, aggregates, and water was produced. Using two sizes of coarse aggregates 1 inch and ¾ inch it was cured for seven and fourteen days, respectively. The compressive strength of the porous concrete was measured once the curing process was complete. The results for the 1-inch size gravel after curing for 7 days varied between 996 to 1279 PSI on average. However, the results of its 14 days of compression testing ranged from 900 to 1360 PSI on average. On the 28 days of curing the average strength is between 1111-1505 PSI. Upon trying the use of ¾ inch size of aggregates, the results of its compressive strength under 7 days curing was averaging from 1009 to 1137 PSI. Lastly, the compressive strength of 3/4-size gravel after 7 days of curing was between 1009 to 1137. Due to its increased infiltration capacity of 1312.982 inc/hr, 21.883 inc/sec, or 555.829 mm/sec, 0.556 m/sec, permeable concrete has a greater potential to be used as a solution to minimize flooding difficulties. The permeable concrete road must, however, adhere to the required standards for provincial highways because the planned location is a provincial route. However, permeable concrete has a high likelihood of being used to reduce flooding problems in terms of infiltration. The results from the compressive testing machine did not meet the minimum requirements for a provincial road's maximum load-bearing capacity.

Can Trauma Stimulate Growth in an Individual?

The purpose of this study was to determine whether emotional trauma can stimulate growth in an individual irrespective of one’s age. A survey research design was utilized to carry out this study using the PTGI (post traumatic growth inventory). Findings indicate no relation between age and growth post trauma indicating that emotional maturity can take place at any time irrespective of age and we can say that PTG leads to wellbeing, the degree of well-being though still cannot be inferred.

Recycling of plastic waste as a construction material: An experimental study of low-density polyethylene (LDPE) as partial replacement to coarse aggregates in the concrete mixture

This research paper investigated the potential use of low-density polyethylene (LDPE) plastic bags as a partial replacement for coarse aggregates in concrete. This study aimed to reduce waste plastic accumulation in the environment by utilizing it practically and sustainably as a construction material. The compressive, flexural, and split tensile strength tests were conducted on cylindrical and beam concrete specimens with different concentrations of low-density polyethylene coarse aggregates (LDPECA) (10%, 20%, and 30%). The test results show that the compressive strength of concrete decreased with an increasing percentage of LDPECA, indicating that it has a negative impact on the strength of concrete. The split tensile strength also decreased with an increasing percentage of LDPECA, but the flexural strength increased with an increasing percentage of LDPECA. In the study, it was shown that LDPE plastic bags as a partial replacement of coarse aggregate in concrete has promising results, but further investigations and experiments are necessary to fully understand the proper application of LDPECA. Further studies could use lower percentages of LDPECA and use admixtures to account for the loss of compressive strength. It may be possible to reduce the amount of plastic waste that builds up in the environment by adding LDPE plastic waste material to concrete. This may also encourage the use of more environmentally friendly materials for construction.

Spent coffee grounds as partial replacement of fine aggregates in concrete hollow blocks

In the Philippines, general garbage is one of the major issues, and the majority of coffee grounds are thrown away and added to general waste. Therefore, in order to aid the community in lessening its growing waste issue, researchers are studying the use of Spent Coffee Grounds (SCG). The objectives of this study are to design a Non-load bearing Concrete Hollow Block (CHB) with SCG as partial replacement of fine aggregates with the given percentages of 5%, 10%, and 15%, to evaluate the CHB with the SCG in terms of Compressive Strength Test and Water Absorption Test and lastly, to compare the quality and cost of the CHB with SCG to the standard CHB. The study used experimental research to obtain the results needed. The researchers produced CHB with 5%, 10%, and 15% replacement of fine aggregates cured for 7, 14, and 28 days. The study includes Compressive Strength Test and Water Absorption Test that were performed in testing centers. The major findings of the study are: the experimental block with 5% SCG and cured for 28 days was measured to have the highest compressive strength; the experimental block with 15% SCG and cured for 7 days was measured to have the lowest compressive strength; in Water Absorption Test, an increase is seen at the maximum replacement of 15%, and a drop is generally seen between 0% and 5% replacement; it was observed that samples that had been cured for 28 days with 5% replacement had the highest percentage of moisture, while samples that had been cured for 7 days with 15% replacement showed the least amount of water absorption on all samples. Based on the analysis of the findings, the researchers concluded that SCG has the potential as partial replacement of fine aggregates in non-load-bearing CHB if only a significant amount of spent coffee grounds is added.
