Transition from Fluid to Solid: ReExamining the Behavior

Transition from Fluid to Solid: ReExamining the Behavior of Concrete at Early Ages. Concrete is the world's most used construction material. One of the qualities of concrete that makes it an exceptional material for construction is the dormant period that allows for transportation, placement, and finishing.

Effect of casting rate and concrete temperature on

The time for the cancellation of pressure is directly affected by the concrete temperature and materials in use, and occurs shortly after the end of the dormant period of cement hydration.

Curing Concrete Dos and Don'ts Bob Vila

DON'T skip control joints in concrete slabs. These joints should be cut in a quarter of the depth of the concrete slab during the very beginning of the curing process, within 24 hours of the initial pour. Using a metal jointing tool, the control joints can be easily and smoothly cut into the concrete surface as the appropriate distances in the slab.

Letter to Bank manager for Reactivation of your Dormant

The cause of deactivation of your dormant account is mainly because of the zero balance or very low balance in your account (say, below 100) for a long period of time. The bank will, of course, intimate you about the deactivation and about the further course of action on closure of your account if you do not maintain the minimum balance and if

Causes Evaluation and Repair of Cracks in Concrete .

Causes Evaluation and Repair of Cracks in Concrete Structures C racks in concrete have many causes. They may affect appearance only, or they may indicate significant structural distress or a lack of durability. Cracks may represent the total extent of the damage, or they may point to problems of greater magnitude. Their

Effect of Micro Silica and GGBS on Compressive Strength

Silica fume increased the maximum rate of hydration of cement and shortened the dormant period. Khayat, et al (1997) monitored the temperatures of two 100 x 200 mm cylinders for 24 hours. The maximum temperature rise at early ages was not significantly affected by the replacement of cement mass by % of silica fume.
