Concrete is the most commonly used building material due to its high strength, moldability, weather-resistant, and fire resistance, among other benefits. In recent years, there has been a growth in usage of Micro Silica fume. Through Ore sand Bridge building, records show that was concrete. These fabrics are not only environmentally sustainable, but they also have technological advantages on bo...

This paper aims at studying the impact of reaction that occurs between contaminants present in soil and silica fume added on chemical, physical mechanical properties soil. The samples were contaminated laboratory with nickel nitrate (Ni(NO3)2). Silica (SF) was to three different ratios (3%, 5%, 10%). Several experiments conducted study characteristics before after adding results revealed increm...

abstract: Alkali-silica reaction (ASR) is one of the most harmful distress mechanisms that affects durability concrete worldwide. Yet, it has been found ASR-induced expansion and may be prevented by appropriate use supplementary cementing materials (SCMs). Recent studies suggest rice husk ash (RHA), a by-product production, present promising performances as pozzolanic material to enhance blende...

In this investigation, silica fume (SF) was used as an additive material to study its influence on the characteristics of expansive soil. The soil in research prepared a lab by mingling bentonite (50 percent dry weight) with natural According (USCS), classified (CH) liquid limit 67.5 and plastic 29.3%. Expansive mixed different percentages (SF), (8, 9, 10, 11, 12, 13%), experiments were conduct...

In the twenty-first century, most high-performance concretes, and many other ordinary concretes, are now based on blended cements that contain silica fume, slag, and/or fly ash additions. Because the chemical shrinkage accompanying the pozzolanic and hydraulic reactions of these mineral admixtures is generally much greater than that accompanying conventional portland cement hydration, these ble...
