Concrete Production

Lightweight Concrete Structural Design maxit LWA is used in the production of lightweight concrete. Lightweight concrete decreases structural dead loads,which in turn permit longer spans, more slender cross sections and reduced reinforcement. This gives architects, and engineer’s greater freedom when designing structural elements. The low weight of maxit LWA ready mixed concrete reduces transport and formwork costs as well as time and material savings. The bulk densities and compressive strengths of ordinary and lightweight concrete are compared in the graph. Element Design To meet the growing demands recommended by the Egan report, maxit LWA is used in the production of high quality precast lightweight concrete. Floor slabs Building panels Lintels Chimney Systems Lightweight Screeds maxit LWA is used in a selection of low density screeds from 800kg/m3 No Fines Concrete A no fines concrete mix using maxit LWA 4 - 10mm graded material is regarded as a high capacity insulating material and lightweight concrete of very low density. The typical applications include: Aligning slabs and roofs Banking slopes in slabs and on roofs Protection and insulation of pipes and channels Support, draining and insulation for artificial grass fields, sports surfaces and for ice rinks Protective shells over offshore storage tanks The thermal conductivity of maxit LWA no fines concrete is slightly higher than that of loose maxit LWA, in the order of l =0.17-0.22 W/mK. The most common mixing proportions are shown in Fig 1 and compressive strength as a function of density is shown in Fig 2. maxit LWA incorporates the unique combination of lightness with strength and is used in the building industry throughout Europe.
