Abstract
<p>In this study, the strength and heat generation properties of concrete using low burning temperature type cement (LTC) with adjusted mineral composition were investigated. As a result, initial strength development pf LTC was same level as that of ordinary portland cement (OPC), so the compressive strength of normal-strength concrete and high-strength concrete using LTC was almost same value as OPC up to the 3days and 28days, respectively. Although long term strength development of LTC is assumed that calcium aluminate-based hydrates increased due to higher C4AF content in LTC. Regarding the adiabatic temperature rise, ultimate temperature rise of LTC was lower than that of OPC, which is assumed to cause that LTC contains less C3A that has relatively high hydration heat and more C4AF that has relatively low hydration heat compared with OPC. In addition, LTC showed good correlation between the compressive strength and the splitting tensile strength or the static modulus of elasticity, which was same trend as OPC. Furthermore, the autogenous shrinkage of LTC was smaller than OPC.</p>
