Concrete blocks - sand - cement blocks

A 1:2:9 lime-pozzolana-sand mortar about equals a 1:6 cement-sand mortar. Adobe and stabilizedsoil blocks are often laid in a mortar of the same composition as the blocks. Tables 3.16 and 3.17 provide information on the materials required for a cubic metre of various mortars and the amount of mortar per square meter for several building units.

Insulating concrete - Liapor

The thermal insulating properties can be further boosted by adding special types of sand. Here again, Liapor has the solution: Using Liapor sand instead of natural sand makes it possible to reduce thermal conductivity by over 50 percent. Structural lightweight concrete is suitable, for example, for the construction of elegant, wide-span bridges

The Thermal Properties Of Concrete - Civil Knowledges

The thermal conductivity of normal conventional concrete depends on its composition and when the concrete is saturated the conductivity ranges generally between about 1.4 and 0.5 kcal/m/hr/C. The degree of saturation of concrete is a major factor because the conductivity of water is about 24 to 26 times that of air.

Gypsum Plaster: Its Properties, Advantages & Disadvantages

Gypsum is non-combustible and contains high content of crystal water. In the event of fire, it acts like a barrier and protects the block work, concrete and steel. Gypsum plaster prevents rusting of metal fittings like pipes and increases their durability. Gypsum plaster has low thermal conductivity and ensures energy and power saving.
