This relationship is described in detail in Ch. 4, Sec. 1. 3 Polymer-Modijed Concrete andMortars Equations for Strength Predictions Regardless of polymer type, the compressive strength (UC)of latexmodified concrete can be predicted at polymer-cement ratios of 5,10,15 and 20% by using the binder-void ratio (a) as follows : Polymer-Cement Ratio, 5%: UC= 657 a - 40 10%: UC= 595 a - 88 15%: UC= 474 a - 63 20%: UC= 423 a - 88 These relationships are presented in detail in Ch. 4, Sec. 1. 4 Preparation of Nomographs The water-cement ratio (W/C) and unit cement content (C) of latexmodified concrete can be generally expressed as a function of the bindervoid ratio (a) with every polymer type at each polymer-cement ratio by the following equations: W/C=-ma+n C=qa+r where m, n, q, and r are empirical constants.

S/a: *** Calculated in a saturated surface-dry condition. 2 Equations for Slump Predictions The slump (9) of latex-modified concrete can be predicted with every polymer type and at each sand-aggregate ratio by using slump control factor (cp)as follows: Sf = jq - k(l-s/a) where j and k are empirical constants. This relationship is described in detail in Ch. 4, Sec. 1. 3 Polymer-Modijed Concrete andMortars Equations for Strength Predictions Regardless of polymer type, the compressive strength (UC)of latexmodified concrete can be predicted at polymer-cement ratios of 5,10,15 and 20% by using the binder-void ratio (a) as follows : Polymer-Cement Ratio, 5%: UC= 657 a - 40 10%: UC= 595 a - 88 15%: UC= 474 a - 63 20%: UC= 423 a - 88 These relationships are presented in detail in Ch.

9181show the setting behavior of the latexmodified mortars and concretes respectively. The setting is delayed with an increase in the polymer-cement ratio. The slower setting does not cause inconvenience in practical applications. NR-modified mortar causes the most delay in setting. Usually, the reasons for the setting delay are that the surfactants such as alkylbenzene sulfonates and caseinates contained in latexes inhibit the hydration of cement. 1~ Rheological studies on PVACmodified concrete by Zivicalt21 revealed that the hydration of cement is inhibited by the adsorption of the surfactants on the binder surface.
