Title:
An execution method of a concrete structure
Document Type and Number:
Japanese Patent JP6171377
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a concrete structure construction method using a cement composition capable of yielding a mortar composition having a good unit volume mass, a good filling property and a good trowel workability as well as an excellent surface accuracy, and further to provide a concrete structure construction method using a cement composition capable of forming a mortar cured product having good strength and adhesion properties that are necessary for the integration of the concrete structure with a window frame or a piping and the like.SOLUTION: A concrete structure construction method using a cement composition that comprises: Portland cement; fine aggregate; light-weight aggregate; fly ash fine powder; cellulosic thickener; and material separation reducing agent and in which the light-weight aggregate is expanded polystyrene ground product and pearlite aggregate, the Blaine specific surface area of the fly ash fine powder is in a particular range, and the material separation reducing agent is high molecular weight synthetic co-polymer.
