TOUGHCRETE –P105 COMPARISON OF FLOOR HARDENER TOUGHCRETE-P105
W/S AGGREGATE TYPE FLOOR HARDENER
Industrial flooring requires, high abrasion resistance and high strength, both features most vital for long life of Industrial flooring the thickness of high abrasion resistance layer should be thicker for high performance and life at longer service. The thicker the high abrasion resistance layer, better aging characteristics are assured.

Considering M40 design mix, and cement content @ 350 350 kgs cement per cubic Metre. I cost of Toughcrete-P105 in the top 1" layer @ 5% of the weight of cement works out to Rs.0.76/- sq.ft. only (The cost of Toughcrete-P105 is taken at Rs.18.00 per kgs, quantity of Toughcrete-P105 used per Metre cube being 17.50 kgs ) Here the thickness of the abrasion resistant layer is around 1" thick. The bottom concrete is cast as usual The remaining layer of 1" is prepares using 5% Toughcrete-P105 to the weight of cement and spread on the bottom layer whilst it is still green. The aging characteristics of the Toughcrete-P105 treated surface is far better 1).Due to reduction / elimination of micro cracks which inherently develop on the surface due to shrinkage. 2).Due to inherently thicker Toughcrete-P015 treated surface of the order of 1"which not only imparts higher strength but also greater abrasion resistance layer This combines feature assures greater agin improved service life Using Toughcrete-P105 the surface hardness is due to morphology changes in the matrix, and is through out the matrix volume. Hardness obtained Mohs 6-7 |
The density of grits used for imparting high abrasion resistance is generally in the range of 3.5 kgs to 4.5 kgs per sq. Metre Taking the cost of material @ Rs.10.00 per kgs, the cost per sq. foot of the treatment works out to Rs. 3.34 per sq.ft. The surface hardness is imparted by the surface of the grits which is spread in single or double layer. Due to daily cyclic variance in ambient temperature the grits are likely to loosen under heavy abrasion and high traffic. Once loosened the surface degradation will be accelerated due to single layer or double layer of the grit packing on the surface. This inherently thin layer of high abrasion resistance surface layer of the order of few grit thickness will exhibit far lower life and accelerated aging. Using grit type hardeners, mere surface hardness is obtained on account of the grit surface hardness. Hardness obtained Mohs 6–7.
