Lightweight mortar is prepared by mixing lime or cement as binder, sand, and saw dust, rice husk, jute fibers, coirs, or asbestos fibers. For example, silicate type chemical mortar resists nitric, chromic, Sulphuric or any acidic damages but it cannot prevent the structure against damage by alkalies of any concentration. Type S is the common choice for many below-grade applications, such as masonry foundations, manholes, retaining walls, and sewers, as well as at-grade projects like brick patios and walkways. Type O mortar employed for interior non-load-bearing applications with very limited exterior use. It performs extremely well to withstand soil pressure and wind and seismic loads. A Step-by-Step Guide. This type of mortar is used to pack the oil wells. The constituents of packing mortars are generally cement-sand, cement-loam or sometimes cement-sand-loam.
