Drying Refractory in Boilers___CNBM International Corporation

This curing process is required on all cement-bonded refractory to create the most favorable conditions to complete the chemical reactions of the cement and water. The heat source for the drying of the refractory is the boiler itself. The drying is done during the initial start-up of the boiler.

To conserve Accelerated concrete curing: The basics I

Curing by jacketed heating. These are usually referred to as radiant heating sys-tems. Hot water or steam in pipes transfers heat to the concrete by radiation or con-vection. In these systems the heating medi-um circulates back through the boiler, mak-ing this a more fuel-efficient curing system than steam curing. Products must be covered

Steam Generators, Low Pressure Boiler - Ultimate Washer

A steam generator is used as a source of heat for thawing and de-icing aggregates. This low pressure boiler also speeds up the curing process for pre-cast concrete, pipe, pre-stress, block operations, saturating the curing area with steam, uniformly heating the concrete and speeding up the normal process.

Optimization of steam-curing regime for high-strength

The main objective of the study reported in this paper is to optimize the steam-curing regime of high-strength self-consolidating concrete (SCC). Test parameters included the preset period, the maximum chamber temperature, and the rate of heating. Two SCC mixtures were optimized to secure design compressive strengths of 8700 and 11,600 psi (60

Thermal Curing Of Fresh Concrete | Curing Methods

Temperature of concrete can be increase either by heating the aggregates and water or by injection of steam into the concrete mix. Special care is required in either of the cases especially, the amount of required water for the concrete mix. For this type of curing, special types of frameworks are only used. The framework should be heat insulated.

PDF Curing of High Performance Precast Concrete

Performance of Precast Concrete Although low-pressure live steam curing has been accepted as a standard method of accelerated curing, throughout the world, some specifying agencies require girder manufacturers to "secondary cure" ("wet cure") for a period of three, five or seven days after having completed steam curing.

Quick Cure - National Precast Concrete Association

Conventional live steam curing systems utilize curing cells (kilns) that are either concrete structures or curing canopies made from canvas, Polyweave, etc. Live steam is commonly supplied to the cells through holes in distribution piping or steam hoses attached to steam header lines.
