Book Description
Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report describes a HITEC evaluation designed to determine the basic capabilities and limitations of the Model 4430 gauge, manufactured by the Troxler Electronic Laboratories,Øfor use in quality control and quality assurance procedures for concrete construction. The ratio of water to cementitious materials in a concrete mix is recognized as a prime determinant of the strength and ultimate durability of the concrete. The Model 4430 Nuclear Water/Cement Ratio Gauge is designed to measure the water-to-cement ratio in fresh concrete sequentially. The evaluation was carried out in four phases: computer simulations, laboratory testing,precision and bias evaluation, and field demonstrations.
