2020-2-20  Off-the-Shelf Antifreeze Admixture for Concrete Initial Laboratory Investigation CHARLES J. KORHONEN AND SHERRI A. ORCHINO INTRODUCTION It has long been a goal of the concrete industry to emplace fresh concrete during the winter without ther- mal protection. A

In May 2000, a concrete pedestrian walkway collapsed in North Carolina, injuring more than 100 people. Investigation revealed that CaCl 2 had been mixed into the grout that filled the holes around the steel reinforcing cables inside the concrete, resulting in corrosion of the cables, thus weakening the structure. Based on your understanding of corrosion, explain why the use of chloride ...

Calcium-Silicate-Hydrate (C-S-H) Concrete Sustainability

Concrete sustainability begins at the most fundamental level: understanding the molecular structure of cement paste—calcium-silicate-hydrate (C-S-H), the main product of the hydration of portland cement and the primarily responsible for strength in cement-based materials. News. MIT News: Visualizing cement hydration on a molecular level (June 2021) ...

The use of antifreeze compounds is not recommended. They are not very effective with high lime mortars and may introduce salts, which may cause efflorescence later. A better practice is to warm the sand and water, and to protect the completed work from freezing.

2012-2-18  compound (calcium lactate) appeared substantially improved. The self-healing capacity of pre-cracked concrete slabs sawed from 56 days (2 months) water cured concrete cylinders was determined by taking light microscopic images before and after permeability quantification. For the latter, pre-cracked concrete slabs were glued in an aluminum ring

AbstractTo investigate the properties of antifreeze asphalt mixtures (AFAC), the dense-graded and gap-graded asphalt mixtures, AC-13 and SMA-13, containing 2, 4, 5, 6, and 4 % by weight and 5, 6, 7, and 8 % by weight antifreeze filler, respectively, were used in this paper. In the experiments, Marshall, rutting, bending beam, and immersion Marshall tests were used to study the engineering ...
