Production process for high-strength, fast-setting cement concrete mixture using fly ash and sodium sulfate activant for structural repair

Abstract

The useful solution refers to a production process for high-strength, fast-setting cement concrete mixes that meet the technical requirements for constructing various structures such as transportation, irrigation, and civil engineering projects, and is particularly suitable for repairing structures in highly corrosive environments such as coastal areas. The process includes the following steps: Step 1: Step 1: Prepare the materials for making cement concrete mix, including crushed stone (D), river sand (C), PC50 cement (XM), fly ash (TB), sodium sulfate activator (NS), and superplasticizer additive (SD); Step 2: Mix the cement concrete mixture to obtain cement concrete mixtures with a slump SN of 10-12 cm.
