A mix constituent proportioning method for concrete containing ternary combinations of cements

摘要

This article reports a laboratory experimental programme that investigated the performance of concrete made with ternary combinations of Portland cement (PC) with pulverised fuel ash (PFA), granulated blastfurnace slag (GBS) and silica fume (SF), with the aim of developing a simple concrete mix constituent proportioning method. The test mixes used combinations of these cements that conformed to ENV 197-1. All mixes used gravel aggregated mixes and a superplasticiser to achieve slump class S2 (60-90 mm) to provide characteristic cube strengths from 20 to 60 N/mm~2. Standard cube strengths were measured up to 180 days.
