What Is the Effect of Admixtures on Concrete Strength?

CSEF · 2008 Applied Mechanics & Structures

Justo R. Padron, III · Washington Academic Middle School, Sanger, Fresno County

Overview

Objectives/Goals The objective of the project is to determine if the concrete additives affect the strength of concrete prepared in a controlled enviroment. Methods/Materials The procedure used was testing the compressive strength of concrete cubes of several mix designs. These samples were prepared in accordance with ASTM C109. These samples were cured in a moisture room in compliance with ASTM C511. The samples were then tested by a concrete compression test machine supplied by Technicon Engineering Services. Results The results of the test show that the various concrete admixtures used did increased the strength of the concrete samples. These sample specimens were all prepared in accordance with the ASTM standards for testing in a controlled environment. Conclusions/Discussion The conclusion is that concrete admixtures do affect the strength of concrete. Depending on the type of Admixture used will affect the strength of the concrete differently.
