High strength concrete is being widely used in construction nowadays and therefore, it is important to develop the design parameters for effective use and considerations. The Indian Standard has the equation for prediction of modulus of elasticity (MOE) but it is valid for normal strength concrete only. The modulus of elasticity is considered as a function of compressive strength of concrete and therefore, all the parameters that have influence on the properties of concrete should necessarily have its effects on the value of the modulus of elasticity. MOE depends on the properties of the aggregates, cement paste and their interactions at the interfacial transition zone. There are numbers of equations to evaluate the modulus of elasticity by various International codes and literatures. This paper aims in developing an empirical equation to evaluate the modulus of elasticity for both normal and high strength concrete considering the indigenous aggregates and materials. The analysis considers test results of modulus of elasticity with a wide range of compressive strength of concrete with a total of about 100 test results. Based on the experimental results for granite and calc‐granulite aggregate an empirical equation is proposed for the prediction of MOE and is compared with the empirical equations available in the different International standards. Also the effect of basalt aggregate on modulus of elasticity as compared to granite aggregate is studied.

用花岗岩和方解石骨料评估普通和高强度混凝土的弹性模量

如今，高强度混凝土在建筑中得到了广泛的应用，因此，重要的是要制定出有效使用和考虑的设计参数。印度标准具有预测弹性模量（MOE）的公式，但仅对普通强度混凝土有效。弹性模量被认为是混凝土抗压强度的函数，因此，所有影响混凝土性能的参数都必须对弹性模量值产生影响。MOE取决于集料，水泥浆的特性及其在界面过渡区的相互作用。有各种方程式可用于评估各种国际法规和文献中的弹性模量。本文旨在开发一个经验方程式，以考虑普通骨料和材料评估普通和高强度混凝土的弹性模量。该分析考虑了具有广泛抗压强度的弹性模量的测试结果，总共约有100个测试结果。根据花岗岩和方解石颗粒聚集体的实验结果，提出了一个预测MOE的经验方程，并与不同国际标准中可用的经验方程进行了比较。还研究了玄武岩骨料与花岗岩骨料相比对弹性模量的影响。该分析考虑了具有广泛抗压强度的弹性模量的测试结果，总共约有100个测试结果。根据花岗岩和方解石颗粒聚集体的实验结果，提出了一个预测MOE的经验方程，并与不同国际标准中可用的经验方程进行了比较。还研究了玄武岩骨料与花岗岩骨料相比对弹性模量的影响。该分析考虑了具有广泛抗压强度的弹性模量的测试结果，总共约有100个测试结果。根据花岗岩和方解石颗粒聚集体的实验结果，提出了一个预测MOE的经验方程，并与不同国际标准中可用的经验方程进行了比较。还研究了玄武岩骨料与花岗岩骨料相比对弹性模量的影响。
