Any substance added to concrete other than cement, aggregate (sand) and water is considered an admixture. Although they are not always needed, concrete additives can help in certain situations.
Various admixtures are used to alter the properties of concrete. Common applications include improving ease of application, lengthening or shortening curing time, and strengthening concrete. Admixtures can also be used for aesthetic purposes, such as changing the colour of the cement.
The effectiveness and resistance of concrete to natural conditions can be improved by utilising engineering science, modifying the composition of the concrete, and checking the type of aggregate and water-cement ratio. If this is not possible or if special conditions exist, such as frost, heat, increased wear and tear, or prolonged exposure to de-icing salts or other chemicals, add admixtures to the concrete.
The benefits of using concrete admixtures include:
Admixtures reduce the amount of cement required, making concrete more cost-effective.
Admixtures make concrete easier to use.
Some admixtures increase the initial strength of concrete.
Some admixtures reduce the initial strength but increase the final strength compared to plain concrete.
The admixtures reduce the initial heat of hydration and prevent the concrete from cracking.
These materials increase the frost resistance of the concrete.
By utilising waste materials, the concrete mixture maintains maximum stability.
The use of these materials reduces the setting time of concrete.
Some of the enzymes in the mixture have antimicrobial properties.
Admixtures are added with a mixture of cement and water to help concrete set and harden. These mixtures are available in both liquid and powder form. Chemical and mineral compounds are the two types of admixtures. The nature of the item determines the use of admixtures.
Chemicals are used to perform the following tasks:
It reduces the cost of the project.
It overcomes emergency concrete placement conditions.
It ensures quality throughout the process from mixing to implementation.
Repair of hardened concrete.
