Aggregate strength, gradation, absorption, specific gravity, shape and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of concrete.
Aggregate strength, gradation, absorption, moisture content, specific gravity, shape, and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of concrete.
This paper discusses the suitability of producing concrete with 100%% recycled aggregate to meet durability and strength requirements for different applications.
However, fly ash substitution for a part of the aggregate improved the durability characteristics of the mixture as the amount of fly ash increased.
The present paper reports part of this study, which investigates the effect of size and grading of the coarse aggregate on the durability and the microstructure characteristics of concrete.
The lower capillarity obtained in the new cement paste of the recycled concretes with low w/c ratios isolates the porosity of the recycled aggregate, increasing the durability but with a rise in the cement content.
The effect of the oxidation of iron sulfides contained in aggregates on concrete durability is well known.
In this research, steel slag and ceramic waste is used as a replacement material for natural aggregates and its durability properties are studied.
Also, the BT has been used in assessing the strength and durability recycled aggregate concrete, fine-aggregate concrete containing rice husk ash, and the effect of relative levels of mineral admixture on strength of concrete (Le et al. 2014; Mala et al. 2013; McNeil and Kang 2013; Yehia et al. 2015).
When coarse aggregate with good freeze thaw durability was mixed, air entrained portland cement concrete has the same durability in terms of relative dynamic modulus as ( Coverline{S} A ) cement concrete in a freeze thaw environment.
