PRODUCTION PROCESS OF CEMENT CONCRETE MIXTURE USING CONCRETE MIXING PLANT WASTE SLUDGE TO PARTIALLY REPLACE RIVER SAND COMBINED WITH INDUSTRIAL BY-PRODUCTS

Abstract

This useful solution refers to the process of producing cement concrete mixtures using waste sludge from concrete batching plants to partially replace river sand, combined with industrial by-products that possess mechanical properties and strength meeting the technical requirements for constructing various projects such as civil engineering, transportation, and irrigation works. Step 1: Prepare materials for cement concrete mixture production, including crushed stone (D), concrete waste sludge (BTBT), river sand (C), PC50 cement (XM), superplasticizer (SD), fly ash (TB), silica fume (MS), and finely ground blast furnace slag (XL); Step 2: Mix the cement concrete mixtures, obtaining cement concrete mixtures with a slump SN of 8-10 cm.
