A normal weight concrete weighs 2400 kg per cubic meter or 145 lbs per cubic foot (3915 lbs per cubic yard). The unit weight of concrete (density) varies depending on the amount and density of the aggregate, the amount of entrained air (and entrapped air), and the water and cement content.
You need to determine the dimensions and the type of stone wall you want to build before you can proceed. Determine the height, width and length of the wall. You also need to decide whether you are going to build a dry stack or a wet stack wall. The wet stack wall uses mortar between the rocks or stones to add additional strength to the wall.
• Ease of spread on the masonry unit • Ease of extrusion between courses without excessive dropping or smearing • Ease of positioning of the masonry unit without movement due to its own weight and the weight of additional courses. If a mortar is ‘harsh’, that is of poor workability, the output of craftsmen will be reduced.

Cement-sand screed: composition, methods for performing ↑ The composition of the DSP may be a conventional cement-sand mortar or made from dry mixes. The composition of ready-mix varies for different types of ties.
If you are installing tile, the mortar bed should be 2-3 inches thick on the outer edge and slightly less at the drain. When mixing the mortar use only enough water to obtain a “dry pack” consistency. A good way to tell if you have the right “dry pack” consistency is to make a ball with the mixed mortar similar to a snowball.

Jun 02, 2017 · These cracks are mostly caused by shrinkage of units and mortar on drying, thermal movement of units and mortar and inevitable slight settlement to which every building is subject. Thus, from the view point of rain penetration, bonding property of mortar is of great importance.
Dry unit weight changed between 2098 kg/m 3 and 2214 kg/m 3 for mortar specimens aged 28 days. The dry unit weight of the mortars containing diatomite was lower than the control mortar because of high porosity and the low specific gravity of diatomite compared to the cement.
Mortar mix is not designated by slump or water-cement ratio. It is the optimum moisture content determined by the mason. Mortar that is too dry won’t spread properly which will result in poor bond and incomplete hydration of the cement. Too wet mortar will settle quickly and not easy to trowel.
