The products of our company can better serve the needs of structure load-unbearing, and make the enterprises of light concrete or special concrete more competitive in their fields.

    The parameters of clay haydite are as followed : column strength : 0.7 to 3.5MP, volume weight : 260--600 Kg/m 3 , heat conductivity: 0.23 － 0.55W/M.K, water absorption: ≤ 10%, degree of fire resistance: ≥500, acoustic absorptivity: 0.53 － 0.88. LECA (haydite) is widely applied in the following aspects: the roof grading and heat preservation insulation layer of common buildings, floor covering of villa/high-grade residences, sound insulation and heat insulation of load-unbearing wall, the interior decoration of study room, washroom and resorts, etc. The haydite layer of impoundment sewerage system was popular with its well-developed technique in Japan . It is widely applied in the gardening of top plate in the underground garage by our company. With amounts of microporous from its surface to interior, the haydite performs well in the mechanical strength, water absorption, aeration and fertilizer holding in the application of planting and gardening. The packed prills were shaped into amounts of cavities . There are no dust in dry condition , with great properties in aeration and drainage . It is much better than nature mud , and not easy to be hard, undisassembly and it won’t be muddy water after being soaked. The higher survival rate of plants due to its better performance in aeration and drainage . The full nutrition haydite includes the nutritive elements of N, P, Ca, Mg, S, Si, Fe, B, Mn, Zn, Cu, Mo, etc. . They make the survival rate higher and the life of plant longer. In Europe, the clay haydite is widely applied in roof garden, ornamental garden, children amusement park, square garden, the drainage of golf lawn approach, and replacing traditional mud with haydite in football field lawn.
