Lime in the building materials in the role and the main application
Lime dry shrinkage, so in addition to paint, it should not be used alone Lime in a wide range of applications in civil engineering, the main purposes are as follows: lime milk and mortar lime powder or lime paste mixed with a lot of paint With lime paste or lime powder can be prepared lime mortar or cement lime mixed mortar for masonry or plastering works lime stabilized soil will be lime powder or lime powder mixed with a variety of crushed or the original loose soil, the mixing, compaction and curing after the mixture, known as lime stabilized soil It includes lime soil, lime stabilized gravel, lime and gravel Clay particles on the surface of a small amount of active silica and alumina react with calcium hydroxide to produce hydrated hydrated calcium silicate and hydrated calcium aluminate, so that the clay impermeability, compressive strength, water resistance is improved Widely used as the basis of the building, the ground cushion and road pavement base silicate products to lime (lime powder or lime powder) and siliceous materials (sand, fly ash, volcanic ash, slag, etc) as the main raw material, after mixing, mixing, molding and curing can be made after the brick, Blocks and other products Because of the internal cementing material is mainly hydrated calcium silicate, so called silicate products, commonly used sand lime brick, fly ash brick and so on
Lime condensation hardening slow, low strength, poor water resistance
Lime water retention, good plasticity, engineering is often used to improve the water retention of mortar to overcome the shortcomings of cement mortar poor water retention
