COMPUTER-BASED TRAINING PROGRAM ON Micro Concrete Tiles TARA Tile Maker
Introduction The mortar used is a mix of Cement, fine sand, coarse sand and fine aggregate Micro Concrete Tiles are made from cement mortar, which is vibrated on a table at a controlled frequency and set on a mould to shape. • The mix consists of: • 1 part cement • 2 parts of graded sand • 1 part of stone grit smaller than 6mm in size
Competitive Advantages • MCR Tiles offer many advantages over other sloping roof materials, such as: • G.I sheets • Mangalore tiles • Wooden shingles • Slate • Asbestos • Highly cost effective • Durable - they have the life of concrete • Lighter than other roofing tiles; hence require less understructure • Easily Installed • Additionally, MCR Tiles: • Can be colored to specification • reduce heat gain • noiseless during rains • free from asbestos CLICK

Building with MCR Tiles MCR roofs are constructed in a conventional manner using rafters and purlins made from wood or steel. Rafters are according to the shape and size of the roof. The purlins are welded at a distance of 40 cm from each other. MCR tiles are secured by tying them to the purlins with G.I. wire. The angle of roof slope should be at least 22 degrees. Greater inclination of upto 30 degrees is preferred for more aesthetic appeal and in high rainfall areas. Standard architectural details for gable and hipped roof ridges, eaves, side over-hang and valleys can be used for MCR roofs, as well. Design Data for MCR Roofs 13 Tiles per sq.m. 32 kg. per sq.m. Tiles needed for 10m of roof: length 50 nos.;width 25 nos.
