Lab No.4: Mortar Mix Design
Executive Summary
This lab was a combination of multiple procedures. The first was batching the mix
design which we made before the lab started, then measuring the flow, fabricating the cubes,
letting them sit for 7 days and th

1. Cracking is a problem with large concrete structures because cracking can create
problems with the permeability of the concrete in relation to freezing and thawing. An
increase in permeability due to cracks can create large uneven v
Lab No.2: ASTM C29
Executive Summary
The ASTM C29 test method is used to determine to the bulk density and
percentage of voids of a sample of course aggregate. In our case, this testing of course
aggregate is needed to help determine the proper mix design
Lab No.10: Coupon Test
Executive Summary
The test method for lab 10 uses a combination of two ASTM's. The first is ASTM
E8, which is a standard for how to do tension testing on metallic materials
specifically steel in this labs case, and Either ASTM A36,
Lab No. 7: Moisture Content, Specific Gravity, Shrinkage Percentages, and Strength
testing of Wood
Executive Summary:
The test method for lab 7 is entirely from the ASTM D198, which is the standard test
method for static tests of lumber in structural size
Lab No.5: Capping, Compression Testing of Concrete Cylinders
The purpose of this lab is to understand and complete a stress testing and capping of cylindrical
concrete specimens. The concrete specimens used are the ones made in a previous lab; they are

Lab No.3: ASTM C127
Introduction:
An important aspect of being a civil engineer is to understand and be capable of
designing and making a mix design. During this laboratory experiment students were asked to
design a concrete mix design based on the requir
