Effect on the hardness paving block by adding gomuti and pumice stone.

Abstract

Paving block is a cement product and been used as the alternative of asphalt. It has been used intensively for parking area, village road and so on in Indonesia. Paving block is also known as concrete block or conblock. Absorption of water to paving block installation system can maintain ground water balance and strongly support go green. It is also echoed nationally as well as internationally. This research will test the compressive strength of paving block considering the paving block function must also be able to support the heavy load on it beside the good absorption. The development and test will be using two types. First, it will be added the fibers of gomuti 3% and pumice stone 10% with additional aggregate 1.5% sikament additive. The second one will be the same but increasing the pumice stone to 20%. This research is expected to get paving block wearing high and light.
