Valuable Details About Concrete Plasticizer

By William Collins


All materials are naturally flexible. Therefore, the hardness and toughness of the contents should not be interpreted to mean it cannot be changed. With adequate knowledge of chemistry, you will note that chemicals referred to as plasticizers help increase the plasticity of the material. This is by reducing the forces of attraction between the molecules and in the process, lowers the magnitude of frictional forces. Years ago, there were thousands of plasticizers, but many have now become extinct. Some of those still used are concrete plasticizer.

The working capacity of concrete is improved by adding plasticizers. The strength is indirectly related to that of water. In mixtures with little water, it becomes hard and thus difficult to mix and work with. These chemicals are used when aluminum material is blended in properly to improve strength. This leads to strong and fiber reinforced material that is easy to blend and work with.

Depending on the chemical used, the amount added has a direct effect on the quality of the end product. Excess plasticizer leads to segregation of concrete and eventually surfaces collapse. The active ingredient in the chemicals is adsorbed onto the cement particles causing a negative charge hence repulsion between particles. Long molecules wrap around the cement particles, get a profoundly negative charge and repel each other strongly.

Although the use of these agents may seem expensive, the benefit is noted years later, and they surpass the initial cost. The walls established withstand torrential rains, earthquakes, hurricanes, thunderstorms and strong winds. The inclusion of the chemicals is economical as it reduces the amount of cement used in the overall process. Such houses are thus smooth, firm and need little maintenance.

Houses made from cement and rocks earlier incorporated with plasticizers are smooth and intact as no cracks are formed. The plasticizers not only increase the strength of but have thermal altering capabilities. Under the hot weather, the temperature at which they can break is raised and cracks not formed. It increases the temperature at which surfaces expand to their breaking point and makes sure that the lines of weakness along the rock elements are not altered.

The chemical agents help the building remain firm throughout the winter season. Due to the low temperatures, contraction occurs, and as the molecules come close together, some surfaces are stressed more than others and making a building incline to one side. Plasticizers are added to control the magnitude of the forces working against each other and ensure the cement does not reach a breaking point.

Use of cement-mixed plasticizers contributes greatly to good health. Surfaces form an excellent residing area for bacteria that later cause illnesses because they meet the suitable characteristics for survival. By using these chemicals, they inhibit the growth of bacteria by altering their growth conditions. This can be by lowering temperatures and absorbing water.

When the plasticizers are used correctly, their benefits are durable. There is no repair for surfaces made of high-quality rock-cement mixtures. Softeners are a potential endocrine disruptor, and their use should, therefore, be controlled. A building made of treated cement-rock elements will not stand firm forever as the plasticizers loss their strength due to old age. Therefore, consider a durable agent and regularly inspect your surfaces for cracks.
