Compressive strength of concrete containing furnace blast
1.Introduction. Concrete is one of the most commonly used construction materials used in different types of structures because of its undeniable advantages (Boğa et al., 2013; Kioumarsi et al., ).In recent decades, several studies have been conducted to develop sustainable concrete by partially replacing Ordinary Portland Cement (OPC) with
Cement The major cements: composition and properties
Coloured cements are made by grinding 5 to 10 percent of suitable pigments with white or ordinary gray portland cement. Airentraining cements are made by the addition on grinding of a small amount, about 0.05 percent, of an organic agent that causes the entrainment of very fine air bubbles in a concrete. This increases the resistance of the

Portland Cement Types and Specifications ANSI Blog
The distinct types of portland cement are defined through ASTM C15022: Standard Specification for Portland Cement, which distinguishes them by purpose. The standard types of portland cement are: Type I for general purpose. Type IA same as Type I, but when air entrainment is desired. Type II for moderate sulfate resistance.
Stabilization of Lateritic Soil with Portland Cement and
The lateritic soil sample was stabilized by adding cement by weight at rates of 3%, 6%, 9%, and 12% to the nonstabilized soil sample. The sand was also used to stabilize the soil sample at 15%, 30%, 45%, and 60% by weight. The laterite was additionally stabilized with varying percentages of both cement and sand.
