The study aimed to enhance the technique of deep mixing with new method that will help
in engineering and construction in developing fast water absorber material in building
microstructure that is highly exposed at high water content. The purpose of this study is to
develop a concrete block with different ratio to observe the behavior in physical and
mechanical. This study employed four methods; Firstly, fly ash- cement mixture, secondly,
soaking of bricks to observe water absorption, third, curing time and lastly, testing of bricks
concrete and fly ash mixture. This mixture composed of 3 different ratios 1:2:4:50,
1⁄2:1:2:4:55, and 1:1:2:4:60 in this ratio we can observe the behavior of the fly ash as
admixture to cement. Nowadays, construction of microstructures like canals and drainage
become more challenging as per the weather changes, using fly ash as admixture will lessen
the days of curing time, knowing that fly ash is a fast water absorber. This study also
observes the behavior of fly ash admixture to cement in physical and mechanical. This
paper specifies the different method of constructing microstructures and the behavior of fly
ash at different ratios, the stability and workability is also observed in this study.
