BUENDIA, GENEVE CHRIS C. and CANIYA, ALYSSA JEAN L. Comparison of Coal Fly Ash and Mill Scale as a Supplemental Cementitious Material for CHB. Undergraduate Thesis. Bachelor of Science in Civil Engineering, Cavite State University, Indang Cavite, May 2017, Adviser: Engr. Renato Cubilla.
The study was conducted from August 2016 to May 2017 at the College of Engineering and Information Technology, Cavite State University, Indang, Cavite to compare coal fly ash and mill scale as supplemental cementitious material for CHB. Specifically, it aimed to; 1. determine the effects of weight, density and chemical properties of CHB incorporated with fly ash and mill scale in its compressive strength; 2. determine the optimum mix proportion of coal fly ash and mill scale for concrete that will give the highest strength for CHB; 3. compare the compressive strength of fly ash with that of mill scale; 4. compare the cost of the standard CHB available in the market and CHB with fly ash and mill scale as supplemental cementitious material; and 5. provide tarpaulin. The authors gathered data from related topics and researches. The materials used in the production of CHB were sand, portland cement, coal fly ash, mill scale and water. Proportion by weight was used in the mixture proportion of cement, sand, coal fly ash and mill scale. The design mix ratio of cement and aggregate used in this study was 1:7 and was limited to seven different mixtures; Treatment A, control mix using mixture of concrete wherein no coal fly ash or mill scale was added; Treatment B, 80 percent cement and 20 percent coal fly ash; Treatment C, 70 percent cement and 30 percent coal fly ash; and Treatment D, 60 percent cement and 40 percent coal fly ash; Treatment E, 80 percent cement and 20 percent mill scale; Treatment F, 70 percent cement and 30 percent mill scale; and Treatment G, 60 percent cement and 40 percent mill scale. As revealed, the conventional mixture, Treatment A achieved the highest compressive strength after twenty-nine days of curing followed by the Treatment B with 20 percent coal fly ash. Increase in strength was more evident at 20 percent replacement level of coal fly ash with cement, Treatment B. It can be deduced that the amount of coal fly ash or mill scale incorporated in the production of CHB largely affects the compressive strength of the sample. For CHB with coal fly ash, Treatment B surpassed the standards imposed by the Philippine Trade Standard Specification but for CHB with mill scale, as the volume of aggregates increases, the strength of the sample also increases however all the samples formulated with mill scale obtained a low compressive strength. Thus, CHB containing 20 percent coal fly ash could be used for non-load bearing structures.
