Properties of Foamed Mortar Prepared with Granulated Blast-Furnace Slag
Foamed mortar with a density of 1300 kg/m³ was prepared. In the initial laboratory trials, water-to-cement (w/c) ratios ranging from 0.54 to 0.64 were tested to determine the optimal value for foamed mortar corresponding to the highest compressive strength without compromising its fresh state properties. With the obtained optimal w/c ratio of 0.56, two types of foamed mortar were prepared, name...
متن کاملGround Granulated Blast Furnace Slag
1. Ground Granulated Blast Furnace Slag Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron o...
متن کاملImprovement of Early Strength of Cement Mortar Containing Granulated Blast Furnace Slag Using Industrial Byproducts
In the field of construction, securing the early strength of concrete (on the first and third days of aging) has been an important problem in deciding the mold release time (i.e., shortening the construction time period). Therefore, the problem of reduced compressive strength in the early aging stage caused by mixing granulated blast furnace slag (GBFS) with concrete must certainly be resolved....
متن کاملinfluence of sodium oxide on properties of fresh and hardened paste of alkali-activated blast-furnace slag
:the aim of this work is to investigate the influence of sodium oxide on properties of fresh and hardened paste of alkali-activated blast furnace slag from isfahan steel plant. the silica modulus (sio2/na2o) of activator was adjusted at 0.6 and a number of mixes were designed in such a way to contain different levels of sodium oxide including 1, 2, 3, 4, 5, and 6% by weight of dry slag. the mos...
متن کاملEffect of Slag, Natural Pozzolana and Metakaolin on Mortar Properties
The objective of this study is to examine the effect of substitution of cement by three different mineral additions, on the mortar rheological and mechanical properties. This experimentation, considers the fineness of mineral additives with a constant workability. Ordinary Portland Cement was partially replaced by different percentages of slag, pozzolana and metakaolin of 10, 20 and 30%. The ob...
