To receive equally strong concrete of the same mobility with the use of superplasticizer C-3, and without it, one cubic meter of concrete spent 15 per cent less cement. This is achieved by reducing the quantity of water, but through the use of plasticizer retained the desired mobility of the concrete. Without any prejudice to the strength of future reinforced concrete and reinforced concrete structures increases the mobility of the concrete mix, this is especially true for monolithic construction, where vengeance used concrete pumps, which are required for normal of concrete P4-P5. Increase the final strength characteristics up to 25 percent. With improved workability is no need of fresh concrete vibrating! Ability without special Problems pour gustoarmirovannye design: narrow formwork walls, columns and so on. Preparation of concrete high-density (high tightness), which positively affects the watertightness reinforced concrete and reinforced concrete structures in general. Improved frost resistance up to F350 and crack. Reduces shrinkage of hardening concrete or concrete products.
Ability to obtain high-strength concrete products and concrete, with indices of compressive strength over 100 MPa! For example: the classic concrete mark 350 has a compressive strength of only 25 MPa. That is – is four times smaller. Moreover, the resulting concrete is more than mark used for mixing cement. Factories producing concrete products derive their benefit from the use of plasticizers by reducing the temperature in the chambers or reducing the time of steaming. And this substantial energy savings, accelerated turnover and as a consequence – increase in production volumes. Increased adhesion reinforcement and concrete is approximately 1.5 times. But there is a plasticizer and very good effect on the concrete. One of these – a slight slowdown in terms of concrete hardening.
Can be considered a negative effect, can someone, and he seems positive, but the essence is. To compensate sometimes slowing the action of plasticizers are special supplements – curing accelerators. It is they and display graphics normal hardening of concrete in the usual level. To date, more and more frequently used complex additives in concrete. As a rule, they are two-component. For example: based on plasticizer-3, and in the appendage curing accelerator, or Air-additive, or microsilica, etc.
