Concrete cement floor sand and ash treatment method

Analysis of the causes of sand and ash on concrete cement floor:

1, mortar consistency is too large (that is, water cement ratio is too large), the greater the ash ratio, the lower the strength of cement mortar. So in the construction of water consumption is too much, will greatly reduce the surface mortar strength, people walking on the surface will appear loose cement ash. Water-cement ratio is generally between 0.2~0.25, and the actual construction water-cement ratio is greater than 0.25, because the cement mortar with water-cement ratio less than 0.25 is more difficult in construction.

2, process arrangement is not appropriate, as well as the underlying too dry or too wet, causing the ground pressure light too early or too late, calender, early hydration of cement is just beginning and gel were fully formed, free moisture also is more, also can appear on the surface of floating, and disturbance had hardened surface, thus greatly reduce the surface strength and anti-wear ability.

3, improper maintenance, entered the stage of hardening cement, the hydration of cement will continue, and the cement particles inside, hydration also constantly improve the deeper cement mortar strength, when the cement hydration because of a lack of moisture and hydration effect, will slow hardening speed even stop hardening, the impact strength of cement mortar and dehydration and antiwear ability.

4, the finished product protection is not good, cement floor mortar strength has not reached a certain strength on people walking or the next process of construction, so that the ground suffers from friction caused by sand, cement mortar floor or due to freezing damage adhesive force, the formation of loose particles.

5, raw materials do not meet the requirements, cement label is low, sand particle size is too fine will also appear cement mortar surface layer sand.

Let's discuss the solution of cement ground sand and ash. Changxin is sealed concrete curing agent for concrete of sand dust up research and development, it can penetrate into the pores of concrete, the effective active ingredients can react with the composition such as the silicate cement, concrete forming silica gel, that the substance does not dissolve in water are both filled concrete pore, increase its strength, and blocked the water seepage channel on the other hand, The corrosion resistance of concrete is greatly enhanced. In addition to increasing strength, corrosion resistance, prevention and control of sand, concrete sealing curing agent construction ground after different polishing treatment can make the original dark dumb concrete ground looks smooth, smooth, beautiful.

CX212 concrete sealing hardener products are widely used in concrete, concrete block, mortar, aggregate wear-resistant ground, terrazzo, gypsum, all exposed surface, old and new, rough or smooth surface, in petrochemical, metal smelting and other industries and warehouse, workshop and wear-resistant ground has been widely used. Its specific performance is as follows:

1, make concrete sealed, hardened, wear-resisting;

2, make concrete dustproof, permanent luster;

3, make concrete reduce high maintenance cost easy to clean;

4, improve the performance of concrete;

5, to overcome the toxicity of oily products;

Therefore, Changxin concrete sealing curing agent is not only a kind of products that can improve the wear resistance of concrete, but also a kind of products that can improve the life of the floor and make it dustproof and sandproof. Concrete sealing curing agent products have good use effect and are suitable for various occasions. Therefore, it has been widely used in the market and widely praised by people.

After local surface has the sand, don't rush to make decoration workers in the above batch of wipes or do concrete cushion layer, to cover up the sand, that will make its appear empty drum, floor will be convex or bow outward exposure dust from the floor seam, but check whether the ground has been batch layer, for a number of layer and have craze empty drum, to eliminate; Cement element pulp and the wall ash on the ground in construction drop, be bored with child to wait on the ground, want to clear uproot, undertake reinforcing processing to the ground with concrete curing agent next, after waiting for its solidify, do the construction job on its again.
