Forte: shrinkage compensated lightweight screed Laterlite

Latermix Forte is a lightweight, shrinkage-compensated screed with a semi-dry consistency (damp soil). Lightweight screeds made with Latermix Forte are ideal for the renovation of existing floors and slabs, as they reduce overloads and, thanks to their compensated shrinkage, are suitable for appliion on large surfaces without joints.. Latermix Forte is a ready mix bagged mortar,

EFFECTS OF THE CLARY SCREED AND TUBE FLOAT ON

The screed, used without additional water, resulted in reduction of roughness and was not considered detrimental to the surface mortar. The tube float, normally used with a fog-spray of water, had little effect on roughness, and resulted in a substantial reduction in quality (compressive strength) of the surface mortar.

Cook (1989) showed that, for compressive strengths in excess of 69 MPa (10,000 psi), smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used
