This research investigated the effects of using a substandard fly ash as partial cement and/or fine aggregate replacement on basic and durability properties cement-fly mixtures. Experimental results showed that utilizing led to increase in water requirement autoclave expansion pastes. The strength activity indexes passed requirements TIS 2135 ASTM C618. Utilization higher mortar bars stored sod...

Conventional pervious pavement materials (PPM) that consist of cement and aggregate are known for poor durability due to their brittle behavior. Thus, enhance the durability, we fabricated polymeric PPMs from durable abundant polyurethane (PU) undertook mechanical microscopic characterizations. PU-based PPM samples with varying sizes were produced examined test compressive strength water permea...
