In the course of this reaction, called hydration, crystals radiate outwards from cement grains and mesh with other adjacent crystals or adheres to adjacent aggregates.
Higher-quality concrete is made by lowering the h2o-cement ratio just as much สหคอนกรีตอัดแรง as is possible without sacrificing the workability of clean concrete. Usually, applying considerably less water makes a greater high-quality concrete presented the concrete is properly placed, consolidated and cured.
