Overview of concrete waterproof admixture:
Concrete waterproof admixture is a chemical admixture added to cement.After the cement is hardened,its volume will expand to compensate for the shrinkage and tension of the steel bars,thereby generating prestress and completely filling the cement gap.Cement waterproofing agent can be directly mixed into cement,concrete and mortar.The bottom surface of the product can form an excellent hydrophobic layer.When water splashes on the surface,it will roll off in the form of water droplets,acting as a lotus leaf.The mixture of water and blowing agent is called a pre-foaming solution.The pre-foaming solution and compressed air are supplied through the spray gun;
Foaming agent can be used with all types of cement,and can only be mixed into cement or sand-gravel mortar to produce foamed concrete of various types and uses.Its cost accounts for a small proportion of the total cost of foam concrete,usually only 1-3%.
There are several characteristics:
1.Efficient water reduction and enhancement functions.
2.High-efficiency impermeability function:Mixing with concrete waterproofing agent can effectively improve the pore structure of concrete,and at the same time,the gel will be precipitated to block the internal capillary channels of concrete.Compared with no waterproofing agent,the impermeability performance can be increased by 5-8 times. Has a permanent waterproof effect.
3.Improve the workability of the mortar:it can improve the workability of the freshly mixed mortar,with a low water flow rate and significantly improve the workability of the mortar.
4.Benefit analysis:It has the function of replacing lime paste,overcoming hollowing,shelling,reducing floor ash,saving labor and improving efficiency.
5.Retarding effect:It can delay the rate of cement hydration heat release and effectively prevent concrete from cracking.
6.Saving cement:Under the premise of maintaining the same strength and slump as the benchmark concrete,10% of cement can be saved.
7.A wide range of applications,used for foamed concrete,mortar,paint and other substrates,and cement with multiple marks.
Application of concrete waterproof admixture:
What is the scope of application of concrete waterproofing admixtures?
The concrete waterproofing agent significantly improves the impermeability and waterproof function of concrete,and the impermeability level can reach P25 or more.It also has the effects of retarding,early strength,water reduction,and crack resistance,and can improve the workability of fresh mortar:it can replace lime paste.It is especially suitable for concrete for roof of bungalows,large-volume waterproof concrete,hydraulic concrete,waterproof mortar,etc.It can completely cure roof leakage,wall dampness,and ground water seepage.It is the cheapest,ideal and reliable preferred material in China.
Price of concrete waterproof admixture:
The price of concrete waterproofing admixtures will vary randomly with the production cost, transportation cost, international situation, and the market supply and demand of concrete waterproofing admixtures.

Technical parameters of concrete waterproof admixture:
(1) The dosage range is 0.2-0.4%,and the specific dosage should be determined by a small amount of experiment.
(2) Mixed on site,first mix with stone,sand,cement and other admixtures once,then add water to mix.
Precautions for concrete waterproof admixture.
(1) When replacing cement or adding new cement,a concrete compatibility test should be carried out.
(2) When mixing with other additives, please confirm their compatibility first.
(3) Proportioning should be made according to the mix ratio,and the construction specifications should be strictly followed when pouring concrete.
(4) Like conventional concrete, maintenance must be strengthened in accordance with construction specifications.
(5) For waterproof concrete in corrosive media,when the anti-corrosion coefficient is less than 0.8,anti-corrosion measures should be taken.The surface temperature of the hydrophobic concrete structure should not exceed 100°C,otherwise protective measures must be taken to cut off the heat source.
Packaging and storage of concrete waterproof outer packaging
(1) 200kg plastic drum or customized according to customer requirements.
(2) Store at 5-30℃,avoid contact with strong acids and alkalis.
(3) The shelf life is 24 months.
