Renewable by Fine Aggregate in Block Cement

Abstract

The purpose of this research is to produce a high strength street-paving block. It enables to Compression Strength and to take the waste material from laboratory to recycle being a new one by Mortar Mold (size 5 x 5 x 5 cm.). It is used to compensate the Replacement Material for Fine Aggregate for two type that are Powdered Lightweight Concrete and Granite Dust to mixed by the designed ratio (increase/decrease for 10 percentages of Replacement Material for Fine Aggregate) for nine ratio. The duration of curing concrete for all of the periods of time are 7, 14 and 28 days. That is each period in 30 block to compare each category of Replacement Material for Fine Aggregate which is Powdered Lightweight Concrete and Granite Dust (only) for 3 samples by Mortar Mold and period of time at the same time. This is found that the ratio between cement : Powdered Lightweight Concrete mixed with the Granite Dust : water with a ratio percentage of Powdered Lightweight Concrete against the Granite Dust  to be 50 : 50. It can be Compression strength to be 122.52 ksc. at 28 days curing time is most suitable for street-paving.
