Flooding is a common problem in Bacoor, Cavite, especially in areas affected by rapid development, limited open spaces, and inadequate drainage. This study explored the use of cocopeat as an admixture in concrete and its potential to help improve water absorption and infiltration for flood mitigation. An experimental approach was used to compare regular concrete with concrete containing 5% and 10% cocopeat. A total of 54 concrete specimens were prepared and cured for 7 days and 28 days. The specimens were tested for workability, compressive strength, water absorption, density, and porosity.

The results showed that adding cocopeat increased the water absorption and porosity of the concrete. The 10% cocopeat mixture had the highest porosity, measuring 20.3% after 7 days and 17.7% after 28 days. It also showed the highest water absorption among the mixtures tested. In terms of compressive strength, the 10% cocopeat mixture performed better that 5% mixture and the control mix. This may be related to cocopeat's ability to absorb and retain water during the curing process. All the findings suggest that cocopeat can be a useful and sustainable admixture for concrete when used in suitable amounts. Its ability to hold water and create more pore spaces may help improve infiltration and reduce surface runoff making it a potential material for flood mitigation applications in Bacoor, Cavite.
