Softener for concrete with their hands: the proportion

The cement slurry made of cement, water, sand and filler. Plasticizers when added to the solution to improve its quality. This addition makes the viscous solution, elastic and plastic. The result is a high strength cement in 15%.

Softener for concrete can be done independently. With the addition of a plasticizer the water will not come out at the top. Therefore, the solution can be used longer. setting process is faster and does not crack upon drying. Reduced shrinkage of concrete during its solidification.

How to make a plasticizer with their hands?

On sale is a ready-made mixture. But many homemade options apply. Previously added chicken egg proteins. This increases the strength of buildings. But such an additive in the solution will cost "a lot of money."

Most of the added PVA, shampoo, laundry detergent or lime. Each supplement of - reacts differently to the solution.

Lime

The added lime mortar. Lime protection against mold and mildew concrete. It improves the quality of the concrete and does not respond to temperature changes. Elastic obtained solution is easy to operate even on a vertical surface. Lime prevents concrete from cracking.

Minus: Strength drops, used for lightweight structures only.

For interior applications proportions and lime solution (1: 1). Before adding lime you need to repay. First, sand is mixed with cement (M400 or M500), and then add lime (lime water).

For exterior applications other proportions solution (1: 6).

Liquid soap

Per sack of cement necessary to add a cup of liquid soap. Suitable foaming agents too. Soap increase solidification process. Adding only at the beginning and previously diluted with water. The same effect is obtained with detergent.

Minus: Foam is formed while stirring. In this case, we have to wait until it settles.

PVA glue

Added to the finished mixture (200 gr. a bucket). Mixed sand and cement first and then water is added and then the PVA. Adhesive mixing becomes transparent and not visible. Screed adding PVA solution better fills the cracks, voids. It obtained solid foundation without cracking.

Suitable only universal glue (PVA - MB). 1 kg. Adhesive costs about 90 rubles. some say that PVA is afraid of ultraviolet (destroyed). But when added to cement its properties change, and he brings great sunlight.

Tile adhesive with the addition of PVA is good because it makes the solution in the sealant. Improved waterproof properties.
