The Cracking Sensitivity of a Na-Geopolymera large experimental campaign that has been carried out at LGCGM, the mechanical properties of Na-geopolymer are investigated as well as its cracking sensitivity at early age. This last depends on several parameters studied in the present project: tensile strength, Young’s modulus, and delayed defor

Crack Control of Upstream Polder Face Using Calibrated Thermo-mechanical Simulations of reinforced upstream concrete face of a polder. The face is made of cast concrete blocks, 15?m long, 2.5?m tall and up to 2.5?m thick. First, the paper summarizes design of two concretes with low hydration heat and their strength evolution, basic creep, calorimetry data, and freeze-thaw resistanc

The Cracking Sensitivity of a Na-Geopolymerts obtained for a Na-Geopolymer are compared to those of a Portland cement-based mortar. From restrained ring tests, it appears that the cracking sensitivity is lower for Na-Geopolymer. This behavior is mainly due to a low Young’s modulus, a fast stabilization of autogenous shrinkage and a high creep capacity.

BLAND

Design, Evaluation and Specification for Concrete Mixtures with Low Potential for Crackingnd laboratory testing are necessary for crack mitigation. During concrete production, efforts to maintain control of batch water and water-to-cementitious ratio are paramount. Results presented in this paper will compare the performance of concrete mixtures with low and high potential for cracking in both the laboratory and field.
