Aerated concrete block autoclave (also called AAC autoclave or autoclave for AAC blocks) is a large, heavy-duty pressure vessel and key equipment to fabricate autoclaved aerated bricks and aerated concrete. AAC autoclave is widely used in autoclaved curing of concrete materials such as aerated concrete block concrete pipe pile, lime sand brick
Cement Standards and Concrete Standards ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
The Architect/Engineer has the option to define when to terminate curing based on testing of the concrete surface. Refer to ACI 201.2R, "Guide to Du-rable Concrete," and ASTM STP 169C, "Significance of Rest and Properties of Concrete and Concrete-Making Materials," for information. 2.1
1.1 This specification covers autoclaved aerated concrete (AAC), a cementitious product based on calcium silicate hydrates in which low density is attained by the inclusion of an agent resulting in macroscopic voids, and in which curing is carried out using high-pressure steam.
The Architect/Engineer uses and supplements the provisions of this reference specification as needed by designating or specifying individual project requirements to which provisions of this specification apply. This document provides requirements for alternative methods for curing concrete.
These autoclaves are held too much greater standard than autoclave systems used for vulcanizing, wood treatment, concrete curing, etc… as most of the parts produced in a composites autoclave end up as parts on the planes we all travel on and in the military protecting our troops.
The air content of the concrete shall be 6% plus or minus 1% by volume based on measurements made on concrete immediately after discharge from the mixer in accordance with ASTM, C-138, C-173 or C-231. 8. MIXING: Concrete shall be mixed in a batch mixer for not less than 1-1/2 minutes after all the materials are in the mixer drum.
Curing plays an important role on strength development and durability of concrete. Curing takes place immediately after concrete placing and finishing, and involves maintenance of desired moisture and temperature conditions, both at depth and near the surface, for extended periods of time.
