More importantly, using a w/c ratio higher than 0.37 in concrete mixtures might also affect the durability of such concrete.
Current guidelines) also recommend the use of SCMs in SCC mixtures as partial replacement of Portland cement to enhance concrete workability and compressive strength.
Twelve VA based concrete mixtures were developed by incorporating 0, 20, 30, 40, and 50 % of VA as replacement of cement while keeping a constant total binder content of 400 kg/m.
The water to binder ratio ranged from 0.35 to 0.45.
In addition, global warming is a major problem for todays and future development and most industries are shifting toward sustainable and green practices.This paper presents the results of a laboratory investigation of self-consolidating concrete (SCC) containing sustainable technologies.Twelve mixes were prepared with different combinations of fly ash, slag, and recycled asphalt pavement (RAP).Fresh and hardened properties, as well as durability characteristics of the 12 mixtures demonstrate that VA can be used to develop SCC with acceptable properties and that it is possible to produce SCC by using 20–50 % VA as cement replacement.However, the authors indicated that replacement level of Portland cement by VA should be selected carefully in combination with water-to-binder ratio in order to achieve desired compressive strength, setting times, and durability.One of the most important properties of concrete is its compressive strength.
