Lime silica sand silicate cement and use technique method thereof in tubular pile production

Abstract

The invention provides lime silica sand silicate cement and a use technique method thereof in tubular pile production. The lime silica sand silicate cement is obtained by the following steps: mixing lime silicate cement clinker, silica sand, quicklime, gypsum and the like in a certain proportion; and then grinding. The use technique method is as follows: the cement is used for replacing high-label silicate cement or ordinary silicate cement, and a tubular pile is produced by using a steam maintenance process. By using the cement, the concrete in the tubular pile under the normal-pressure maintenance condition has good early strength property, and the strength of the concrete in the tubular pile under the autoclave maintenance condition.

Description

technical field [0001] The invention relates to a production technical method of concrete pipe piles. Background technique [0002] In the prior art, pretensioned prestressed concrete pipe piles ("pipe piles" for short) include: prestressed concrete pipe piles (i.e. PC piles, the concrete design strength is C60 grade), prestressed high-strength concrete pipe piles (i.e. PHC piles , the concrete design strength is C80 grade), prestressed concrete thin-walled pipe piles (ie PTC piles, the concrete design strength is C60 grade). The cementitious material used in the production of pipe piles is portland cement above grade 42.5 or ordinary portland cement.

The early strength is low or the production is relatively complicated or the technology is immature, so some patented technologies have not been well promoted and used
