Low-Temperature Curing Strength Enhancement in Cement-Based Materials Containing Limestone Powder.
With the ongoing sustainability movement, the incorporation of limestone powder in cementitious binders for concrete in the U.S. has become a subject of renewed interest. In addition to accelerating the early age hydration reactions of cementitious systems by providing additional surfaces for nucleation and growth of products, limestone powder is also intriguing based on its influence on low-te...
متن کاملFlexural Fatigue Strength of Steel Fibre Reinforced Concrete Containing Blends of Limestone Powder and Silica Fume
Based upon the statistical distribution of flexural fatigue life data and flexural fatigue strength of the steel fibre reinforced concrete (SFRC) containing blends of limestone powder (LP) and silica fume (SF), the influence of these inserts on the flexural fatigue performance of concretes is probed. Concrete mixes were proportioned to replace 30% cement with these mineral inserts in different ...
متن کاملEffect of Limestone Powder on Microstructure of Ternary Cementitious System
The pressure to reach sustainability favours the development of ternary composite cement. The synergistic effect on mechanical behaviour at 28 days between limestone powder (LP) and pozzolanic additives, i.e. fly ash (FA) and blast furnace slag (BFS), has been documented. In order to better understand the synergistic effect, this article investigated the effect of LP on the microstructure of PC...
متن کاملLimestone and Silica Powder Replacements for Cement: Early-Age Performance.
Developing functional concrete mixtures with less ordinary portland cement (OPC) has been one of the key objectives of the 21st century sustainability movement. While the supplies of many alternatives to OPC (such as fly ash or slag) may be limited, those of limestone and silica powders produced by crushing rocks seem virtually endless. The present study examines the chemical and physical influ...
متن کاملEco-friendly Blocks by Blended Materials
In spite of broad improvements in construction technology, cement is still stayed as binding material for construction purposes. Cement industries are the main sources for the contribution of carbon dioxide (co2) into the atmosphere. So, there is a need to use new materials as binders (green binders) in substitute for cement, which leads to reducing the production of cement. In this study, fly ...
