Supplementary cementitious materials (SCM) are increasingly used in concrete for economical and environmental reasons. However, the durability of reinforced concretes against, example, corrosion induced by carbonation varies. Here, phase assemblage various cement pastes with/without SCM (slag, fly ash metakaolin), carbonated accelerated conditions (1.5% CO2 65% RH) or not, has been investigated...

In order to reduce the amount of cement required, improve workability, mechanical properties, and durability, have a positive environmental impact, supplementary cementitious materials are frequently utilized as partial replacement for in concrete mixes. this experimental investigation, effects employing waterproof supplemental such flyash, silica fume, nano along with water reduction agent wer...

Two mine tailings are evaluated for their potential as supplementary cementitious materials. The were milled using two different methods – ball milling 30 minutes and disc durations ranging from 1 to 15 minutes. modified R3 test was carried out on the quantify reactivity. reactivity of is greater than those tailings. Strong correlations obtained between duration, median particle size, amorphous...

Various self-healing methods for concrete, such as the use of supplementary cementitious materials, adhesive agents, mineral admixtures, and bacteria, have been suggested to date, and each of these has merits and demerits. Among these, however, the use of cementitious materials may be appropriate due to their good healing efficiency, low cost, and compatibility with the cement matrix. In this s...
