Silicate treatments can be used to improve the properties of concrete surfaces. Higher abrasion and chemical resistance will especially extend the service life of concrete floors.
1. The visual state of pure HPMC is fluffy and the bulk density is small, ranging from 0.3-0.4g/ml; the adulterated HPMC has better fluidity and heavier hand feel, which is obviously different from the original appearance.
As a new type of water-reducing agent after naphthalene-based, melamine-based, aliphatic-based and sulfamate-based water-reducing agents, polycarboxylic acid-based water-reducing agents have been widely used in many important projects due to their many unique performance advantages.
In ready-mixed mortar, the addition amount of HPMC is very low, but it can significantly improve the performance of wet mortar and is a major additive that affects the construction performance of mortar. Reasonable selection of cellulose ethers of different varieties, different viscosities, different particle sizes, different viscosity degrees and added amounts will have a positive impact on improving the performance of dry mortar.
VAE Re-dispersible Polymer Powder is dispersed in the gypsum slurry and then forms a film, filling the pores of the slurry and intersecting with the gypsum hydration products to form a three-dimensional network structure, making the gypsum structure more dense.
Lithium carbonate is a carbonate of lithium, with a molecular formula of Li2CO3, a molecular weight of 73.891, a melting point of 720°C, a boiling point of 1342°C, a density of 2.11g/cm3, and a white powder appearance. It is an inorganic compound, colorless monoclinic crystal, slightly soluble in water and dilute acid, and insoluble in ethanol and acetone. It is used as a raw material for ceramics, glass (1552, -81.00, -4.96%), ferrite, etc., and components are sprayed with silver paste. It is used medically to treat depression.
Lithium silicate, also known as lithium water glass, is a compound formed by combining metallic lithium with a silicate structure. The molecular formula is: Li2SiO3. Lithium silicate is an odorless, tasteless, transparent liquid with a pH value of around 11, which is alkaline. Soluble in water and alkaline solutions, but insoluble in alcohol and organic solvents.
Hydroxypropyl methylcellulose is used as a water-retaining agent in cement mortar and retarder for mortar pumping.
The compatibility between polycarboxylate polymer powder and cement is not good, and the concrete mixture is prone to problems such as segregation, bleeding, increased slump loss, and shortened setting time. This makes the concrete mixture unable to be transported and poured normally, reducing the strength of the concrete. and durability.
VAE Re-dispersible Polymer Powder is a water-soluble re-dispersible powder, a copolymer of ethylene and vinyl acetate, with polyvinyl alcohol as a protective colloid.
Interior wall putty powder generally has a viscosity of 100,000. Cement mortar has higher requirements for adjustment, and a viscosity of 150,000 is easy to use. In addition, the most critical function of HPMC is to lock in water, followed by thickening.
Since Portland cement is often used in mortar, it is characterized by low early strength and high late strength.
