Influence of Humidity on the Material Properties of Cement Paste with Fly Ash in the Mutual Relation 50/50

摘要

The different properties of building materials are often caused by their varying humidity respectively water saturation levels. The cement paste is a porous material. The cement paste mixed with fly ash is highly porous material whose properties depend on the amount of pores in the material and the state of saturation. Basic material properties like strength, Modulus of elasticity, volume weight are compared in article for cement paste with fly ash for two states, saturated and dried materials. The ratio of cement and bulk ash was 1:1. Article presents results of experiments in age of 1 month after production.
