摘要

摘要本研究旨在探讨引入不同矿物掺合料对混凝土力学性能的影响。研究的重点是优化新混凝土和硬化混凝土的性能，特别关注坍落度、单位重量、进气量、抗压强度、抗拉强度、弯曲强度和弹性模量等因素是如何受到混凝土混合料中不同矿物外加剂的影响的。使用了不同的矿物掺合料，即硅灰、石灰石和超细石膏，在试验中，每种矿物掺合料取代了25%的水泥。并对混凝土的新鲜性能和硬化性能进行了比较。

Influence of Mineral Admixtures on the Mechanical Properties of Fresh and Hardened Concrete

Abstract This research aims to investigate the effect of introducing different mineral admixtures on the mechanical properties of concrete. The research is focused on optimizing the properties of fresh and hardened concrete, looking in particular at how factors such as slump, unit weight, air entrancement, compressive strength, tensile strength, flexural strength and modulus of elasticity are affected by different mineral admixtures in a concrete mix. Different mineral admixtures are used, namely silica fume, limestone and ultra-fine gypsum, and for the tests each mineral admixture replaced 25 % of the cement. The paper also compares the performance of the fresh and hardened properties of concrete.
