We work with contractors and owners to provide information for plastic shrinkage cracking. We provide detailed information on rate of evaporation and how and when to take precautions to avoid early moisture loss in fresh concrete pours. How to determine early moisture loss. Avoiding early moisture loss in concrete is critical early loss of hydration water may reduce surface PSI by up to one/half.
Testing Ready Mix Concrete
We provide hands on workshops for ACI Field Grade I testing Certification , the review course provides workbook instruction and hands on step by step review of
ASTM C 172 Sampling
ASTM C 143 Slump
ASTM C 138 UNIT Weight and Density
ASTM C 31 Making and storing field cylinders
ASTM C 1064 Temperature of concrete
ASTM C 231 Air test with the pressure meter
ASTM C 173 Air test by volumetric method
We also provide demonstrations for the Super Air meter
We provide several Guidelines for concrete

P H LEVELS IN CONCRETE
In Chemistry the PH scale measures how acidic or alkaline concrete is. High on the PH scale is about 11 for concrete. This is important as lower PH levels will lower the concretes ability to withstand effects of chemicals such as de-icing salts. We understand and work with clients to solve this and early carbonation issues. When reviewing mix designs we carefully review admixtures and air content. Our knowledge of mixes can help achieve the needed durability requirements.

ACI Flatwork Training
More projects and owners require training and certification for concrete finishers. ACI offers one of the best. Mike has been involved with ACI 640 Flatwork certification for over 15 years he himself has held the Flatwork finisher certification for over 20 years. Our review workshop covers all aspects for the examination
Training may be done in-house and additional fees will apply for ACI EXAM and test
