Mr. Torichigai, Kajima Corporation, introduced a dam construction project in Japan
The report presents an investigation of mechanical and durability properties of concrete by adding iron slag as replacement of sand in various percentages. The X-ray diffraction analysis carried out in this paper gives a deeper insight in the mineralogical constitution and behavior of such slags when used for construction purposes.

· difference in the level of deicer scaling that occurred in slag cement concrete versus OPC concrete (Dubovoy, et al, 1986). Afrani and Rogers (1994), on the other hand, recorded much greater scaling loss for concrete with high slag cement replacement compared to OPC concrete. Also noted was a difference in deicer scaling resistance apparently
In concrete, processed steel and blast furnace slag provide a sustainable alternative to primary aggregates in the production of lightweight or dense ready-mixed concrete. Blast furnace slag can also be used to make Ground Granulated Blast-furnace Slag (GGBS) which …
· 50% slag sand. 2. Slag sand, having higher water absorption than natural sand, required more water per m3. 3. It was noticed that the mixes using slag sand were harsher than mixes with natural sand only, and extra dose of SP in such mixes led to bleeding …
· The 28 days strength for conventional concrete is found out to be 1.697 MPa and that for 15% rice husk ash in concrete is 1.380 MPa. It shows the 24.41 % improvement from conventional concrete. For other percentage of rice husk ash the strength is getting low, thus optimum percentage for use of RHA is 15%. CONCLUSION.
· furnace slag are industrial by-products which provide excellent binding properties to concreteand serve as a replacement of cement . ... It is used with water and sand to make mortar or mixed with sand, aggregate and water to form concrete. The manu- ... imum at 60 days for concrete with no replacement of cement with fly ash.

Abstract: In the present study an investigation is made on properties of concrete by partial replacement of Cement with Ground Granulated Blast Furnace Slag (GGBS) and Fine Aggregate with Quarry Dust (QD). Ground Granulated Blast Furnace Slag is a by-product of Iron and Steel industry which is produced in large quantities as a solid waste.
· using copper slag as a replacement of fine aggregate on the strength properties. M25 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0% to in concrete. The test results indicate that compressive strength of concrete
The new application of copper slag as a partial substitute for sand also triggered the change of the Singapore's Aggregates Standards which allows both natural and non-natural aggregates, including recycled aggregates, in concrete, thereby, opening the door to the use of more recycled/waste materials in concrete production.
This paper reports the results of some experimental studies on the use of non-ground-granulated blast-furnace slag (NGGBFS) as fine aggregate in concrete. Two groups of concrete samples were produced.

· by-product from the blast-furnaces of iron and steel industries. GGBS is very useful in the design and development of high-quality cement paste/mortar and concrete. Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast-furnaces are fed with controlled mixture of iron-ore, coke and
· granulated blast furnace slag is better replacement of cement than various other alternatives. The rateof strength gain in slag replaced concrete is slow in early stages but with proper curing the strength goes on increasing tremendously. The compressive strength decreases when the cement replacement is more than 50%. Use of slag or
· iron blast-furnace slag will be covered. While all applications of blast-furnace slag in cement will be mentioned at least briefly, the major emphasis will be on the combinations of Portland cement with the slag (Portland blast-furnace slag cements) and the ground glassy slags that can be used for this application. Most of the discussion
