EFFECT OF SODIUM FORMATE AND SODIUM CHLORIDE ON CONCRETE

The evaluation involved visual assessment of the concrete surface after each immersion-oven dry cycle and after every ten cycles of the freeze-thaw test. The test results indicate that the saturated sodium formate (98%) solution caused the most severe damage to the concrete. (Author/TRRL) Corporate Authors: Alberta Transportation. 4999 98th Avenue

Calcium Formate - an overview ScienceDirect Topics

Calcium formate sodium nitrite blends have been used extensively, with the added advantage of anti-corrosion properties claimed for their use. 75 Measurement of the electrode potential of steel embedded in concrete at constant applied current density is one method of monitoring the passivity of the steel.

Evaluation of South Dakota Deicer No. 2 and Calcium ...

Evaluation of the materials was performed by determining the interfacial shear strength of ice formed on portland cement concrete (PCC) substrates that have been treated with aqueous solutions of the various salts. A carefully defined test procedure was developed; details are given in the next section. Briefly, the test involves treating the substrate with an aqueous solution of the test material and then, after it has dried, forming ice on it in a Teflon retaining ring. This ice is then broken from the substrate with a shearing force, thus giving a measure of the ultimate yield strength. The measurement sequences performed include one series at a fixed application rate of 0.22 g/cm2 [equivalent to 200 lb per lane-mile (lb/Im)] as a function of test temperature and another series at fixed test

Formates as Alternative Deicers

literature report that calcium formate causes spalling of concrete has been verified at the Celanese Chemical Company. This essentially eliminates calcium formate as an alternative deicer. In a California study, sodium formate was likewise found to cause spalling (10). However, in the Bjorksten study, a similar problem was encountered with CMA. It was traced to application on uncured concrete. Thus, it was thought possible that sodium formate would not spall cured portland cement concrete. Subsequent experiments at Celanese have proven that sodium formate does not spall concrete. It has also been shown that sodium formate

Evaluation of Concrete Durability Performance with Sodium ...

This paper presents an enhanced performance in concrete impregnated with silicate compound. Two different types of impregnant materials (inorganic and combined type) are applied to concrete samples with different strength grade (21 MPa and 34 MPa). Through lab-scale test, improved performances in impregnated concrete are evaluated regarding porosity, strength, chloride diffusion coefficient ...

2019-3-21  In the presence of calcium formate, the time point of the exothermic peak was postponed. However, the end of the induction period was not affected for the samples with an M s of 1, though it shifted to an earlier time point for the samples with an M s of 0.7. Nevertheless, calcium formate did not influence the hydration kinetics of the AAS.
