Pore Block Non Cement As Solution To Rain Founding

Abstrak

In general, the manufacture of paving blocks uses a mixture of cement, coarse aggregate, fine aggregate and water which is mixed into one and then shaped. The results of previous studies showed that the coefficient of runoff that occurred on land with ordinary paving block covers was 0.41 - 0.46 or there was an increase in surface runoff by 171% - 215% compared to hard soil without paving block covers. This indicates that there is a potential for increased puddles when it rains. Based on this, it is necessary to increase the ability to pass water from paving blocks in the form of modifying the character of the existing paving blocks by making porous paving blocks coupled with the application of innovative materials without cement. This research was conducted with the aim of designing a porous paving block material without cement which is expected to be a solution in overcoming the inundation that occurs. The result of this research show that the test results get a permeability value of 77.36% or in other words a runoff coefficient of 0.22, an infiltration rate of 1.15 cm/s and an average compressive strength of 106.886 kg/cm2.
