Proposed Mix Design System

By using the above-mentioned equations for slump and compressive strength predictions and nomographs for water-cement ratio and unit cement content estimations, an appropriate mix design system is proposed as represented in Fig. 3.4.I 1 

The limits of validity of these equations and nomographs are as follows Types of Materials Used  

Type of cement ordinary portland cement (ASTM-Type I) 

Type of aggregate river sand (size, 2.5 mm or finer) and river gravel (size, 5-20 mm) saturated, surface-dry 

Polymer-cement ratio (P/C) from 0.05 to 0.20 (5 to 20 wt% of polymer with respect to cement) 

TVpeofpolymer latex forcementmodifien commercial polymer latexes, irrespective of polymer types (containing antifoamers)
