There are four main directions of relieving the oil wells mortars:

• increasing water-cement ratio
• aeration of the grouting mortar with air-gas mixtures
• use of weight light additives [1], [2]
• chemical reaction and air-entraining of components while cementing.

Finely porous foamed ceramic microspheres of the specified size 0.1 to 0.6 mm with a solid and strong shell are used as a lightweight filler.

Thermal floor insulation is an important element of house warming. This is especially true for the first floors of multi-apartment houses and low-rise buildings. It can be done quickly and simply with the help of the screed «Teplopol De Luxe» with foamed ceramics.
