### Glossary

Cement is a hydraulic bonding agent which is obtained by heating, then grinding, a mixture of limestone and clay. Most cements are made from clinker and additives and are usually used in the form of a powder. Cement sets when mixed with water. Combined with sand and aggregates (sand or gravel), it turns into rockhard concrete or mortar. احصل على السعر

### Mix ratio for gravel and cement

Nov 12, 2014Whats the ratio of gravel (premixed sand and stone) to cement for making a good strong concrete mix for a wall foundation? Is 4 gravel to 1 cement a good/stong concrete mix for 450mm deep x 450mm wide wall foundations? Or is it 5:1? There will also be 8mm steel mesh in the foundation too (50mm up off the base).
