Detailed Notes on concrete reinforced retaining wall

In addition to portland cement, concrete may well incorporate other cementitious materials like fly ash, a waste byproduct from coal burning electrical power crops; floor slag, a byproduct of iron and steel producing; and silica fume, a waste byproduct within the manufacture of silicon or ferro-silicon metallic.
