The material ratio is 1:2:3.
The material ratio of cement, pisolite and yellow sand in floor heating leveling is 1:2:3. Because underfloor heating leveling is special, in addition to cement and yellow sand, it is also special. It is necessary to add certain spaces between the pea cores, which is more conducive to floor heating and heat dissipation.
Sanding or cracking is more likely to occur after leveling underfloor heating. Sanding is due to the insufficient strength of the concrete floor. Everyone should pay special attention to the dosage. The causes of cracks are multiple.
Is 4-8 or 8-12 pisolite better for underfloor heating in the north?
The density of concrete is about 1.8 tons /cubic meter. 600×3×0.1×1.8=324 tons. The density of concrete with different sands and gravels and different proportions is slightly different.
When leveling for underfloor heating, attention should be paid to the proportion of sand, cement and pisolite. Although pisolite is good, the quantity should not be too large (usually 2 square meters per pack for leveling, 30 kg). per package). If there is too much pisolite, it will affect the leveling process. The amount of sand and cement used, and sometimes the sand on the ground, is also linked to this! the price of pisolite is about 8-10 times that of melon seed slices. The diameter of the pisolite is preferably 10 to 12 mm.
Whether it is better to use ceramsite or pisolite to level underfloor heating
8 to 12.
Northern floor heating generally uses 8-12mm natural pisolite, because the surface of 8-12mm pisolite is smooth, without edges and corners, and the sizeparticles is uniform.
Pisolite refers to a kind of modern-day building material. It is a stone the size of a soybean. It is generally used for floors and roofs. The particle size is similar to mung beans and is called stone powder in some places.
What diameter pebble should be used when installing underfloor heating?
Polka dot stone is good. Discovered according to Qijia.com query.
1. Pisolite can prevent the floor heating coil from being damaged and make the floor heating temperature more uniform. The surface of ceramsite is rougher than gravel and has a lower water absorption capacity.
2. Pisolite can increase thermal conductivity and has a hard texture. The price of ceramsite is high and the cost of subsequent maintenance is also high.
Pisolite specialized for reunderfloor heating backfill, the required size is about 10mm, with a smooth surface and no edges or corners. Only smooth stones have better thermal conductivity and can better play the role of paving stone production. Based in Linyi, Shandong, pisolite producers for floor heating use natural pisolite, which is sieved twice. Each bag weighs 50 kilograms and the ratio of cement, sand and pisolite is 1:2:3. Say the important things three times, 10mm, 10mm, 10mm.
