effect of granulated slag as sand replacement in concrete
Can groundgranulated blastfurnace be a partial ...
Actually, the usual range is 60 percent replacement. It decreases permeability of concrete. There are tons of research on the effects of GGBFS as a concrete replacement. However if you ask me I like fly ash more. The range is 30 percent replacement however and make sure it is type F not C as C is volatile and vulnerable to aggregatesilica reaction.

transport properties of concrete which are responsible for the resistance against the penetration of external agents potentially aggressive. The effects of glass powder on the concrete properties are compared to those of other mineral admixtures such as class .
Fly Ash, Slag, Silica Fume, and Natural Pozzolans, Chapter 3
Fly ash, ground granulated blastfurnace slag, calcined clay, metakaolin, calcined shale, and silica fume contribute to the strength gain of concrete. However, the strength of concrete containing these materials can be higher or lower than the strength of concrete using .
Is GGBS a good partial replacement for cement in concrete ...
Yes GGBS is a good partial replacement for cement in concrete mix. It is used as a hydraulic binder. It improves the quality and durability of concrete. It is cheaply available as a replacement material. It provides better workability. high resistance to attack by sulphate and other chemicals.
Influence of Slag and Slag Cement on the Strength of ...
摘要: This study is a part of an ongoing research studying the effect of blast furnace slag as a binder and filler replacement on the properties of fresh and hardened concrete. A mix having the density of 1300kg/m3 with a proportion of (1 cement:2 sand), W/C ratio of, a commercially available additive (SP1), class F fly ash and a ...
An Experimental Study on the Properties of Glass Fibre ...
on the use of ground granulated blast furnace slag as partial replacement of is obtained from steel industry is a glassy granular material which is then dried and ground into fine powder. It increases the long term strength, durability and resistance to attack in peaty/acidic environment. From the
Study of Granulated Blast Furnace Slag as Fine Aggregates ...
prepared in blast furnace without blast furnace slags. The use of granulated blast furnace slag (GBFS) aggregates in concrete by replacement of natural aggregates is very promising concept because its impact strength is quite more than natural aggregate. Steel slag aggregates are already being used as aggregates in asphalt paving road m due to
IJETT Performance of Concrete by Copper Slag as Partial ...
This study reports the potential use of granulated copper slag from sterlite industries as a replacement for sand in concrete. The effect of replacing fine aggregate by copper slag on the compressive strength, split tensile strength and flexural strength of concrete are attempted in this work.
Utilization of Industrial Waste Slag as Aggregate in ...
sand by GBF crystallized slag. Tests carried out on cubes of concrete showed the effect of the substituting part of sand by granulated slag (30%, 50%) and the total substi tution on the development of compressive strength. Compressive strength test results at 3, 7, 28, 60 days and 5 months of hardening concluded that the total substitu
Ground granulated blast furnace slag ggbs SlideShare
May 26, 2016· Ground granulated blast furnace slag ggbs. • By use of GGBS 80% of CO2 emission can be reduced. At the same time studies have revaled use of GGBS in concrete partial replacement OPC have increased compressive strenth, tensile strenth, durability and decrese the permiability, embodied enery and cost per cubic meter.
Blended Cement Containing High Volume Ground Dune Sand and ...
This paper presents the results of using ground dune sand (GDS) and ground granulated blast furnace slag (slag) as high volume cement replacement materials. In this study, plain and four blended mixtures were fabricated and cured under normal and autoclave conditions. For the blended mixtures, 40% GDS by weight of the total binder materials and different percentages of slag (15%, 30% and 45% ...
Application of Blast Furnace Slag Sand in Cement Concrete ...
