Vapour maintenance process, the method can solve the above problems well.
To reach above-mentioned requirements, the present invention is adopted the technical scheme that：
A kind of concurrent early strength that improves is provided and exempts from steam protecting method, concrete vibration moulding method uses adhesion type
Vibration moulding, and concurrent additive is added in concrete, concurrent additive includes that concurrent is additional
Agent includes high performance water reducing agent of polyocarboxy acid, super hardening additive.
The concurrent additive include high performance water reducing agent of polyocarboxy acid, super hardening additive and, calcining kaolin and
Sodium tripolyphosphate；High performance water reducing agent of polyocarboxy acid is made up of following component：AEO 600-700 parts, unitary not
Saturated carboxylic acid and its derivative 900-1200 parts, acrylic acid 450-600 parts, initiator 60-80 parts, catalyst 40-50 parts, molecule
80-100 parts of conditioning agent of amount, monoolefin carboxylic acid 100-150 parts, allyl polyethenoxy ether 200-250 parts, methyl alkenyl polyoxy second
300-400 parts of alkene polyethenoxy ether；Super hardening additive is made up of following component：Methoxy polyethylene glycol methacrylate-styrene polymer

Al2O3 contents are more than or equal to 25, and fineness is tailed over less than 5%. with 45um
The concrete vibration moulding method changes former plug-in type vibrating molding mode, is changed to mould side both sides adhesion type
Motor oscillating is molded.Concrete density can be significantly improved, strengthens concrete strength.
The advantage of the method is as follows：
The concurrent additive is added in concurrent production, while coordinating adhesion type vibration moulding mode, is only needed
Electric pole is set to reach demoulding strength by wanting 18 hours, while each age strength of concrete is substantially increased, far beyond original
Design strength value, so as to not only reduce cement consumption, while saving energy consumption is substantially, and can skip steam curing this ring
