Lime substitute is a specially developed additive that replaces lime 100%. The additive gives plasticity to cement mortars, provides excellent astringency, is used to regulate the properties of cement-sand mortars. It is used during plastering works, when laying bricks, foam concrete, aerated concrete blocks, tiles.
What is the principle of the additive for cement-sand mortars?The PROTEX lime substitute works as an air-entrapping additive.
When mixing, air bubbles form a large number of closed air pores in the structure of the solution.
Due to this, the material becomes plastic, retains viscosity and mobility throughout the entire work cycle and during technological stops. The formed air bubbles give the solution hydrophobic properties, while stopping the formation of efflorescences caused by the movement of free water through the capillaries. The additive increases the frost resistance of the masonry or plaster layer. Creates the effect of "breathable plaster" - the wall remains vapor permeable and does not accumulate moisture.
What are the main advantages of using PROTEX lime substitute?increases the strength of the masonry mortar and plaster ensures the adhesion of fresh mortar to the substrate eliminates salting significantly lowers the cost of the finished mortar increases the viability of the mortar before setting solves the problem of lime storage on construction sites prevents the formation of cracks does not cause corrosion of steel reinforcement How to carry out work with the use of additives?
Works with the use of lime substitute are carried out at the base and ambient temperatures from 5 ° C to 35 ° C.
The additive should be introduced into the concrete mixture simultaneously with the kneading water, while reducing the amount of water by 10%, ensuring uniform distribution of the additive by mixing.
What amount of supplement is recommended?For masonry work: 250-500 ml per 50 kg of cement For plastering work: 300-600 ml per 50 kg of cement!
Do not inject into dry components!The use of a detergent, liquid soap, washing powder instead of a lime substitute and plasticizer, which are made on the basis of concentrated sodium chloride compounds and have the properties of "corroding" with cement, leads to the appearance of large efflorescences on brickwork.
The strength of the masonry mortar drops several times, which, in the future, leads to "weathering" and destruction of the masonry.
