Close Proceed. Yanagida and R. Cs showed similar penetration profiles with Cl regardless of cement and sand types. Kondo, Yogyo-Kyokai-Shi, [in Japanese], , 87 3 , p. Ukraincik, D. Alonso, C. Collepardi, in: Quick method to determine free and bound chlorides in concrete.
This measure alone, however, does not necessarily prevent frost damage; if the excavation is backfilled with frost-susceptible soil it may lead to damage from adfreezing. Movements in excess of 4 in. This, while reducing heat loss, can cause deeper ground freezing than previously, particularly where insulation is applied to the interior surfaces of the basement space. Date Published: These crystalline complexes, similar to a gel which grows in the presence of water, block the capillaries of the MORTAR-IC and minor shrinkage cracks, thus preventing water ingress. In recent years, lightweight plastic insulation has been used extensively to reduce ground heat loss and hence depth of frost penetration. Buildings in which crawl spaces are provided between the foundations and the first floor level are also vulnerable to frost action.

Such ground freezing can lead to heaving of buildings located above or adjacent to it. If loss of heat can be prevented or reduced, frost-susceptible soils may not experience freezing temperatures. If such observations indicate that excessive heaving pressures are developing, preventive measures can be taken. Cold air is more dense than warm air and flows into the spaces below ground level, accelerating the extraction of heat from the soil behind the retaining structures.
CBD-182. Frost Action and Foundations
Description: If one of these conditions can be eliminated, frost heaving will not occur. The waterproofing chemicals remain active for the life of the structure, permanently sealing it from water penetration. Frost Action and Foundations. Under these conditions heat flow is primarily horizontal and ice lensing occurs parallel to the walls. The "Freezing Index" is simply the accumulated total of degree-days of freezing for a given winter.
