This work investigated the effects of high water reducing admixtures on some properties of concrete made with quarry dust as the sole fine aggregate. The properties of interest are the compressive strength, workability and the water absorption properties, while the high water reducing admixture used is the Conplast SP430.

The research work carried out included an experimental investigation on strength properties of concrete made with 2.5% to 20% replacement of cement by quarry dust of less than 75 micron particle size. The tests were carried out to find the compressive strength, splitting tensile strength and flexural strength on specimens.
This chapter discusses the use of quarry waste as cement and aggregate replacement, discussing the effects on fresh and hardened properties as well as durability of concrete, including workability, density, compressive strength, flexural strength, splitting tensile strength, water absorption, and chloride resistance.
