Evaluación de la ceniza de cascarilla de arroz como suplemento al cemento en mezclas de concreto hidráulico

Abstract

The investigation raised the use of rice husk ash (CCA) processed in rice plants of the llanos orientales colombianos, as a supplement of a part by weight of the cement, in mixtures of hydraulic concrete, in order to determine the properties Mechanical and physical, such as: resistance to compression, settlement, modulus of elasticity, Poisson relation and analysis of the microstructure of hydraulic concrete. The data were obtained experimentally through the laboratory tests established by the current Colombian technical standards. The proper burning of the rice husk produces an ash with a possible percentage of important silica, which is an element that has good puzolanica activity, effective for the formation of ceménticos compounds that increase the resistance to the Compression of the hardened concrete. And, given that the eastern plains region has the largest sizes of units of rice production (UPA) and crop per farmer in the country, this research approach the study of a solution to the environmental problems and logistical support that occurs at the time of having adequately the husk which is extracted from the paddy, through its use in the improvement of the quality of the hydraulic concrete, which is the most important material in the construction industry.
