Comparison of properties of steel slag and crushed limestone aggregate concretes Article in Construction and Building Materials 17(2):105112 · March .
The slag can replace the cement, saving the cost of production. In today's rapid economic development, the slag discharge is increasing every day. A large number of accumulations in the environment, also cause pollution to the air, soil, water, and cause harm to human health. The steel slag crushing plantg has become a difficult problem in production. Its existence also lets many enterprises headache.
Slag Cement. A distinction is made between limeslag cement, with a content of 10–30 percent lime (by weight) and up to 5 percent gypsum, and sulfateslag cement, with 15–20 percent gypsum or anhydrite and up to 5 percent portland cement or up to 2 percent lime. Slag cement is used in the production of mortars and concretes intended primarily...
I was figuring to do crushing at the mining site, train the crushed ore to a centralized refining setup, and seperately train the stone from the site and slag from refining to a separate recovery setup. but I'm starting to doubt that plan now. I was originally figuring to try to use it as a source of Uranium for stepping up to nuclear.
Slag aggregate having acceptable properties such as crushing value, impact strength and water absorption shall be used in concrete. Incorporating slag in coarse aggregate reduces compressive strength by 2% in 20% replacement, 16% for 40% replacement, 17% for 60% replacement and 19% for replacement.
PART I – PROPERTIES OF BLAST FURNACE SLAG. Our natural aggregates, such as stone and gravel of suitable quality for concrete making, are rapidly becoming depleted in many localities. An artificial aggregate which has had one of the longest service records as a .

Slag cement is a byproduct of the ironmaking process and is composed primarily of silica and calcium. In fine particle form, slag cement displays cementitious qualities similar to those of ordinary portland cement (OPC). Slag cement can therefore be substituted for OPC in a wide range of equal mass replacement ratios.
produced by crushing rock, gravel, ironblast furnace slag, or hydrauliccement concrete." In the RMC Foundation study, aggregate test results indicated that fine aggregate produced by crushing 1000, 3000, and 5000 psi (7, 21, and 35 MPa) concrete meets ASTM C33 specifications with two exceptions:
Adding GGBFS during cement production can increase the strength 28D of cement by 15% 20%, to admix grade cement, and during concrete production, slag powder can replace 10 ~ 50% of the cement, to mix C20 ~ C60 concrete, which has become an important measure to reduce the cost of cement in the international cement industry. Piles of slag are taken and fed by the forklift truck, and .
Using slag cement makes concrete more consistent, resistant to aggressive chemicals and less permeable. Slag cement has been used in concrete projects in the United States for over a century. Over the years, modern designers have been able to improve durability to produce the lowest lifecycle and maintenance costs possible.
A guide to the use of iron blast furnace slag in cement and concrete This Guide to the Use of Iron Blast Furnace Slag in Cement and Concrete produced by the Australasian Slag.....Rock slag can be crushed and screened to a.
The results indicated that the durability characteristics of steel slag cement concretes were better than those of crushed limestone aggregate concrete. Similarly, some of the physical properties of steel slag aggregate concrete were better than those of crushed limestone aggregate concrete, though the unit weight of the former was more than that of the latter.

May 30, 2003· Gravel Driveway Natural 21AA or Crushed Concrete. Is there any issues with using 21AA made from cleaned 11/2" concrete. Crushed concrete 21AA costs about 8/yd and natural costs about 24/yd in my area. I have heard that the crushed concrete will not be as dusty as natural but less dusty than 21AA made from limestone. Any thoughts on the material.

Steel Slag Priced about 24 per ton, steel slag is a byproduct of making steel. To be used as construction aggregate material, it must be crushed and screened to meet gradation requirements. The aggregate material is angular in shape and rough to the touch. Because of its tendency to expand in humid environments, it is best used in drier climates.
Iron and steel slag is effectively used in cement, roadbed materials, concrete aggregate, materials for various sorts of civil engineering work etc. Cement manufactured using blastfurnace slag accounts for more than 20% of Japan's total cement output. Blastfurnace slag cement obviates the need for crushing .
