| dc.description.abstract | Concrete is the most used materials in the world, in most part of the world, shelters are made of concrete. As the population growth increases every year, the need for shelter will consequently increase with the demand of concrete. Cement is an important material in concrete, it acts as the main binder. Cement manufacturing industries contributes up to 6-8% of the global carbon dioxide emission as well as energy intensive process and depletes our natural resources. Due to the harmful effects to our environment, hence the need to reduce the usage of cement is crucial. In this research, the materials, rice husk ash (RHA) and ground granulated blast-furnace slag (GGBS) were used in concrete as a cement replacement. The hybridization of the materials was done in an optimum ratio to ensure proper replacement value of the materials. Important aspects such as the mechanical strength and durability properties are assessed, and all specimens were fabricated in 3 units to get the average. To gain further understandings on the properties of the binder, a study of microstructural level, such as scanning electron microscopy (SEM) was also conducted. The incorporation of RHA and GGBS in concrete as cement replacement enhances the strength and durability properties of specimens especially at the later curing age, at the early curing age, the overall performance was comparable to the control. It is suggested that the replacement range value shall fall between 10% to 40% to get the optimum performance. Most specimens are refined in terms of pore structure due to the pore fillings effect of RHA, and also the pozzolanic reaction that produces secondary calcium silicate hydrate (C-S-H). | en_US |
