Unformatted text preview: Concrete Mix Designs and Compression Tests CE 206 (C.E. Lab #2) Conducted: January 21st, 2010, and February 16 th , 2010 Submitted to: Prof. Brown, February 25 th , 2010 Tom Wienckowski Lab Group C Members: Andrew Dougan Kyle Fischer Matt Smith Table of Contents Page Abstract 3 Introduction 4 Methods and Procedures 4 Results and Discussion 6 Conclusions 8 Appendix 9 2 Abstract Different types of concrete mix designs provide engineers with the data for how much compression different mix designs can withstand. The objective of this lab was to be familiarized with the general characteristics of concrete and concrete materials and with laboratory methods of manufacture and test of concrete specimens. Also, to determine the effect of varying design mixes and materials, including water, cement, sand, and coarse aggregate, on the consistency of the fresh concrete and on the strength of the hardened material. The concrete designs were mixed and prepared in the lab. Two weeks after the designs were prepared, they were tested in a compression machine. The results were accurate for my groups 3500-psi mix design. The greatest difference between the results and the predicted value was 140 psi. The results will be used to show the accuracy of our mix designs compared to the target strength. Introduction 3 Different concrete designs are used for various different applications in construction and engineering. Since they are so often used in the engineering field, their engineering properties are very important. The water to cement ratio is an important factor to consider while using concrete. Different compression strengths are used for different types of construction and materials in the engineering field. The objective of this lab was to be familiarized with the general characteristics of concrete and concrete materials and with laboratory methods of manufacture and test of concrete specimens. materials and with laboratory methods of manufacture and test of concrete specimens....
