Optimization and performance of air entrained self consolidating concrete
Higher stress levels always caused earlier and more occurrences of brittle fracture.
A prediction model of the damage degree of SCC was proposed by incorporating the test results achieved in the paper.
Salt freeze-thaw had small influences on the surface erosion and relative dynamic elastic modulus of the SCC used in this study.
Under coupling effect of salt freeze-thaw and flexural load, different levels of flexural load were applied on the SCC specimens.
Each series of concrete included three different fresh mixtures.ABSTRACT: The effect of waste latex paints (WLPs) on fresh and hardened properties of cement-based materials is not well understood.In this project, WLPs were not randomly collected from waste collection sites; rather produced to ensure full traceability of composition, then stored in sealed or opened pail conditions to get expired.However, it increased the demand for high-range water reducer and air-entraining admixture.The overall test results indicate that the air-void stability in all fresh self-consolidating concretes was satisfactory.
Search for optimization and performance of air entrained self consolidating concrete:
The modified point-count method was employed to determine the characteristics of the corresponding air-void system.
