    Ettringite was first described in 1874 by J.Lehmann, for an occurrence near the Ettringer Bellerberg Volcano, Ettringen, Rheinland-Pfalz, Germany. It occurs within metamorphically altered limestone adjacent to igneous intrusive rocks or within xenoliths.It also occurs as weathering crusts on larnite in the Hatrurim Formation of Israel. It occurs associated with portlandite

    Nearly half of the sandstones have grain densities close to 2.65 g/cm 3, the density of quartz, suggesting that those sandstones are composed of quartz grains and cement. The remaining sandstones have slightly larger grain densities, most likely due to mixing of quartz with more dense minerals like calcite (ρ = 2.71 g/cm 3 ) or dolomite (ρ

    Properties of Polymer Cement Concrete 1. Highly Impermeable The polymer phase in the concrete will help reduce the porosity and microcraks that are formed in cement matrix. This acts as an additional binding material other than the Portland cement used. 2. High Durability A dense and water tight concrete is obtained by the use of PCC
