CHAPTER TWO - [ Total Page(s): 9 ]Utilization of high-silica corn husk ash (HSCA) as a SCM has the potential to benefit the environment, as well as corn and cement producers. Corn biomass normally left to degrade in the field can now become a commodity. Cellulose-based ethanol production facilities produce the bio-fuel from corn biomass without removing the silica necessary for use as a SCM. The current socio-economic climate in the world requires engineers to consider nontraditional materials to help minimize environmental impa ... Continue reading---
CHAPTER THREE - [ Total Page(s): 3 ]In order to get the corn stalk, the leaves and sheaths were removed to expose the stalk. The stalks with a straight stem, free from pest and disease, without insect bites, without apparent defects on the surface of the stems, and with uniform color were selected. The mean length of the corn stalks was 2100mm, the pitch of corn stalk was taken artificially and made into a column shape for use as test specimen with a cross-section of 10mm by 10mm and a length of 100-150mm. Figure 3.2 shows the cor ... Continue reading---
CHAPTER FOUR - [ Total Page(s): 5 ]CHAPTER FOURRESULTS AND DISCUSSIONCorn stalk ash (CSA) is not a good pozzolanic material, since it has the combined percentage composition of silica (SiO2), alumina (Al2O3) and iron oxide (Fe2O3) of 18.78%, which is less than 70%. It therefore does not satisfy the requirement for use as a pozzolana according to ASTM C618(2005). ... Continue reading---
CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE CONCLUSIONS AND RECOMMENDATION5.0 CONCLUSIONSThis study has dealt tremendously on the investigation of the characteristics of cornstalk ash blended cement. The findings of this research has led to the following conclusions:• The study revealed that Corn stalk ash (CSA) is not a good pozzolanic material because it does not satisfy the standard specified by ASTM C618(2005).• The compressive strength of the concrete cubes increased with curing period and amou ...
