Abstract

In this paper the displacement behavior of single span pre stressed concrete beams have been studied numerically by different methods. Six pre stress concrete beams with parabolic curve cable profile for different amount of pre stressing force were analyzed by Macaulay’s method, Matrix method (STAAD.PRO) and FEA method. The results of all these three methods are compared with each other.

Keywords

Cable-Profile, Prestressed Concrete, Deflection:Friction, Finite Element.

Abstract

In this study effects of different water proofers on compressive strength of cement concrete has been made using experiments. Total 108 cubes were cast using normal, 60% of 20 mm and 40% of 10 mm size of coarse aggregates having three water proofer Dr. fixit, Roff, Aqua Roff proportion of 4ml/kg cement. NDT of the cast cubes using rebound hammer and UPV have been also carried out. All the cubes were tested for ultimate load using compression testing machine and compressive strengths of the cubes are calculated. Based on these data, comparative studies have been carried out to quantify the effect of different water proofers on the compressive strength of the concrete. From these data, salient conclusions are drawn.

Keywords

Concrete, Normal Aggregates, Water Proofer Chemicals, Compressive Strength.
