Shrinkage-compensating cement waterproofing agent
Expansion-resistant cracking waterproofing agent
High-efficiency waterproofing agent is made of rigid inorganic waterproofing materials. It has many functions such as efficient waterproofing, moisture-proof, impermeability, crack resistance, etc. This product is mixed into concrete, and its generated substances penetrate into the interior of the concrete through the water existing in the pores of the concrete, and interact with the free lime and oxides in the capillary pores. A chemical reaction occurs to form dendritic crystals that are insoluble in water and seal the capillary network, pores and micro-cracks in concrete. Make the structure denser, greatly reduce the permeability coefficient, and improve the impermeability of concrete
[Main technical indicators]
, the amount of concrete mixed with cementitious materials ~
, low alkali content, No corrosion hazard to steel bars, no impact on water quality
, impermeability grade, frost resistance grade,
, concrete limited expansion rate is greater than
[Product applicable scope]
This product is particularly suitable Impermeable waterproof concrete, large-volume waterproof concrete, hydraulic concrete, waterproof mortar, etc. prepared at the construction site.
[Usage Precautions]
, Testing implementation standards or,
, The product should be placed in a dry place to prevent moisture. The product has a shelf life of six months.

Technical performance of shrinkage-compensating cement waterproofing agent
Water-reducing enhancement. Add the recommended dosage of this product to concrete. When the cement dosage and slump are the same, it can By reducing the amount of mixing water, the strength of concrete increases significantly, the strength can be increased, and various physical and mechanical properties of concrete can be greatly improved.
, bleeding rate ratio ~.
, air content ~.
. Compensate shrinkage. When the dosage is ~ of the amount of cement, the limited expansion rate is between , and stress can be established in the reinforced concrete, thereby effectively compensating the shrinkage of concrete and reducing shrinkage cracks in concrete.
, anti-permeability index can be achieved.
, The initial setting time of early retarded concrete is extended ~ (it can be adjusted according to the engineering requirements to reduce the cement hydration heat, thereby reducing the internal temperature rise of the concrete, which is beneficial to reducing the temperature difference between inside and outside.
, the fluidization effect is the same at the same time Under the conditions of cement dosage and water-cement ratio, adding the recommended dosage of this product can significantly increase the slump of concrete.
Instructions for use
It is an off-white powder and does not contain carrier.
, The dosage of this product is ~ the amount of cement, commonly used dosage. Using the internal mixing method, it can replace the cement in equal amounts.
, The curing time after concrete is poured should not be less than days, and it is best to cover and protect it during the curing period.< br/> , Before use, the concrete must be tested and qualified before use.
Scope of application
, Suitable for Portland cement, ordinary Portland cement, and slag Portland cement. Can be used in the following projects Middle silos, reservoirs, water corridors, tunnels, dams, underwater structures and other projects that require high anti-cracking and anti-seepage requirements and have certain hydrostatic pressure.
, foundation projects, roof projects, repair projects , post-cast concrete.
, highways, overpasses, airport runways, parking lots and large-area projects that require fewer expansion joints.
, can be used in maintenance projects such as roofs and sanitary stations.
Packaging and storage of shrinkage-compensating cement waterproofing agent
Packed in woven bags, kg/bag, with a shelf life of more than one year. If it becomes damp and agglomerates due to storage reasons, the agglomerated parts should be screened out and inspected before use.
