CA mortar powder is how of

CA mortar powder CA mortar powder material formula 1. About the composition of CA mortar cement + packing + water reducing beautiful seam an agent + expansion beautiful seam an agent + emulsified asphalt formula everyone more clearly. In fact, many small factory can produce according to the components, but in fact what all supply of CA mortar have been several big tianfu, Thomas nagel, shield stone and so on to do, obviously high iron this big projects consider far is fitment materials, product composition and the reasonable distribution of the stability of the raw is always the first. 2. To talk about all kinds of raw materials, not to mention the of cement and emulsified asphalt and cement as well as the packing, Slag powder and fly ash, etc. ) Beauty seam an agent, expansion mixed easily segregation, if even become a big problem. Usually basic cement and sand grading is not reasonable, mix of CA mortar the settlement of all tracks is impossible to do it, so for the sand particle size, especially gradation is strict. It is better to 0 sand. 075 - 2 mm continuous gradation, and fine particles more good, why? 3. Sand particles even if you take the thin, the root of cement particles than there must be some fault. Emulsified asphalt and cement sand can be mixed evenly, to a great extent whether you can fill with cement and emulsified asphalt cement with small fault clearance between the sand. This will have to use more small packing, such as the particle size, superfine slag powder, ultra-fine fly ash, basically the particle size, 0. 1 - 10 microns, and can increase the early strength, increasing elastic modulus and frost resistance. 4. So we must not imagine so simple, the CA mortar, in fact, the solution of these problems can't be a small factory can solve. Although the strength requirement is not high, elastic modulus and frost resistance higher than ordinary mortar requirements.
