Additives are substances we add to mortar or concrete to change its properties according to the needs of each project. Today, you'll learn about 5 of them. Plasticizing additives reduce or maintain the amount of water added to the mortar or concrete, thus reducing the risk of shrinkage cracks. Adding only the necessary amount of water results in greater strength. Superplasticizing additives reduce the amount of water needed in mortar or concrete by about 20% to 25%. Setting accelerator additives are used when we need to reduce the time it takes for concrete to gain strength, achieving high strength in the first few days. Setting retarding additives are also available. They are used when there is a long distance between the plant and the construction site, for example, and also in very cold climates. Finally, we have waterproofing additives, which, as the name suggests, are added to ensure watertightness in the mortar or concrete, preventing infiltration. Additives assist in various stages of the construction process, and to use them, simply follow the instructions on the packaging.
