Abstract

The effect of elevated temperature history due to heat of hydration on physical properties and hydration system in the cement paste were investigated. The elevated temperature in early ages is known to cause stagnation of strength development. Therefore, the degree of hydration of each mineral component as well as hydrates is determined by X-ray/Rietveld analysis and cement paste properties, namely, the degree of hydration of each mineral, the amount of calcium hydroxide, chemically bound water, water content, density of hardened cement paste and mechanical properties were investigated. As a result, compressive strength, young's modulus, and shear modulus of hardened cement paste, regardless of W/C differences, can be evaluated with gel/space ratio of hardened cement paste with a single curve.
