The steel slagGGBS composite mineral admixture is more suitable to be used in high strength concrete than in low strength concrete. As far as the longterm properties of concrete are concerned, the activity index of the composite mineral admixture at the late age should be adopted.
Effects of Manganese as an Alloying Element. Manganese is used as an alloying element for many different applications. Manganese is a key component of steel. In fact, this chemical element is present in all commercially available steels and is responsible for the steel's hardness and strength, but to less of an extent than carbon.
Effects of Crushed Oyster Shell on Strength and Durability of Marine Concrete Containing Fly Ash and Blastfurnace Slag A large quantity of oyster shell is generated every year in coastal regions. Instead of being dumped as waste, after crushing or grinding, oyster shell may be recycled for use in concrete.
slag (GGBS) material is used in the current work to stabilise soil (clay). The main objectives of this research were to investigate the effect of GGBS on the engineering property (optimum moisture content and maximum dry density, plastic limit, liquid limit, compaction, unconfined compressive strength, .
Effect of Local Steel Slag as a Coarse Aggregate on. local steel slag, on the fresh and hardened geopolymer concrete properties. . compressive strength for all mixes at Several cases curing at. 3,7, 28 and 91 days. .. aggregate in fly ash content 450 kg/m3, and molarity M10,.
Our contribution consists at the study of the effect of (0 %, % and %) dosage of an hardening accelerating plasticizer (Plastocrete 160, produced by Sika Aldjazair) on the properties of normal mortar and concretes prepared with portland cement artificial of Hadjar Soud cement factory (Skikda – Algeria) with addition of (10 % and 20 %) of granulated blast furnace slag finely crushed ...
The young modulus, absorbed energy and cold crushing strength of the refractory increased with increase in weight percentage of the clay content. It is observed that there is a reduction in the young modulus, absorbed energy and cold crushing strength as a result of increase in the sintering temperature.
These results indicate that, as long as proper curing is provided during the early days, the effect of the addition of GGBS in reducing the chloride ingress of concrete is able to offset the effect of the lower hydration rate, and consequent higher permeability of the slag concrete at early ages.
Manganese is possibly the most flexible element that can be added to copper alloys. Small additions of manganese are used to deoxidize the alloy and enhance its mechanical strength and castability. In antimony and aluminum, the addition of manganese produces highly ferromagnetic compounds.

The crushing strength of the pellets containing calcium hydroxide and calcium chloride in addition to bentonite was better than the strength of pellets prepared using only bentonite binder. Keywords Pyrite ash, pellet, binder, bentonite, pelletization, wmr 9579
setting time of the concrete. The addition of fly ash causes a slower but longer reaction rate in the concrete. As a result, the heat of hydration is reduced, and the setting time of the mix is delayed. 1. Effects of SCMs: The addition of SCMs to a concrete mixture affects .

OPTIMIZING THE STRENGTH AND PERMEABILITY OF PERVIOUS CONCRETE . ... an endeavour to achieve an optimized mix with adequate tensile strength and porosity. In addition, a relationship was investigated between permeability and porosity of different mixtures. ... bonding, thus reducing the effects of ravelling, while maintaining adequate ...
The soil is A76(5) according to AASHTO classification systems. 5%, 8% and 10% steel slag content (SSC) each by dry weight of soil, was used to stabilize the soil while evaluating the specific gravity, consistency limits, compaction, permeability, uncured and cured strength of the soil.
Because the use of chemical and mineral admixtures in addition to airentraining agents has become common practice, concrete users are always concerned about the effects of these admixtures on the airvoid system and durability of concrete. Effects of water reducers, retarders, and accelerators were widely investigated by many researchers.
Mechanical properties of the refractory specimens were evaluated based on their cold crushing strength. In addition, specimens were characterized in terms of physical and thermophysical properties: density, porosity, thermal conductivity, thermal diffusivity and heat capacity and compared to commercially available refractory material.
