When the concrete is hardened, admixtures lend the following: It accelerates the rate of strength development during the early stage. It increases strength and durability while decreasing permeability. It helps control expansion caused by the alkali-aggregate reaction. It helps improve the concrete's bond with reinforcement or old/new concrete.

The Characteristics of Ready-Mix Concrete & Delivery. Ready-mix concrete is a mixture of paste and aggregates: the paste, composed of Portland cement and water, coats the surface of the fine and coarse aggregates. A chemical reaction, called hydration, causes this paste to harden and gain substantial strength, forming the rock-solid mass ...

The additives are added to a water-cement mixture to increase the life of the concrete, control setting, and hardening and fix the general concrete behavior. They can be powdered or liquid additives. The additives can …

The ingredients required to produce the mix are fed from one end and the mix is collected from the other. The mix is collected by attaching a chute to the opening of the drum. The blades in these mixers also help in the extraction process. non-tilting drum mixers are not suitable for preparing concrete with very large-sized aggregates and for ...

Step 3: Mixing in Water. The amount of water added to concrete is called the water/cement ratio. Though adding more water to the concrete will make it easier to mix, pour, and work with, it actually lowers the concrete strength of the concrete when cured. This is because the hydration creates interlocking crystals and the more water in the mix ...
