    Cement Two series of specimens were prepared, one with ordinary Portland cement (CEM I R) and another ground granulated blast furnace slag cement (CEM III/B N LH) both commercially available in The Netherlands. The chemical composition of both cement types is shown in Table 1; the slag cement contains about 70% Size: KB. A BRIEF REVIEW ON BLAST-FURNACE SLAG AND COPPER SLAG AS FINE AGGREGATE IN MORTAR AND CONCRETE BASED ON PORTLAND CEMENT Alaa M. Rashad Building Materials Research and Quality Control Institute, Housing & Building National Research Center, HBRC, Cairo, Egypt Received: Septem Abstract.

In: Zairyo/Journal of the Society of Materials Science, Japan. ; Vol. 59, No. pp. Author: Satoru Matsuoka, Makoto Kawakami, Toshiki Ayano. 3. Blast-furnace slag is the glassy granular material formed when molten blast-furnace slag is rapidly chilled, as by immersion in water (Virgalitte et al., ). Blast furnace slag (mm to 75 micron) was collected from jindal Steel Plant located at bhilai, Chhattisgarh for replacement to natural sand. The physical properties of blast.

    Keywords: drying shrinkage; review; slag cement. Date: 10/1/ Abstract: This report details the results of a critical review of the literature on the effect of ground, granulated, blast-furnace slag (slag cement) and slag-blended cements on the drying shrinkage of by: Blast furnace slag is a byproduct that is formed during the production of hot metal in blast furnace. If the molten slag is cooled and solidified by rapid water quenching, ground granulated blast furnace slag is formed. When crushed or milled to very fine cement-sized particles, ground granulated blast furnace slag (GGBFS) has cementitious.

The material properties of retested specimens consisting of tailings, cement, and blast furnace slag were examined. The composition of the lead slag, iron slag, and cycloned tailings were determined by inductively coupled plasma analysis. Cycloned tailings were composed mainly of.

Department of Energy)]. Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine -granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing.

Choi et al. used tungsten tailings as a substitute material for cement [9], and acceptable properties of the mortar could be obtained using 10 wt% tailings. The recycling of valuable metals. Potentials of steel slag and copper mine tailings as construction materials E.

Oluwasola1, M. Hainin2, M. Aziz*2, H. Yaacob1 and M. Warid1 The present rate of utilisation of mine. This paper presents a laboratory study on the influence of combination of fly ash (FA) and ground granulated blast-furnace slag (GGBS) on the properties of high-strength concrete.

A contrast study was carried out for the concrete (GGFAC) incorporating FA and GGBS, control Portland cement concrete and high-volume FA high-strength concrete (HFAC).Cited by: of cement is replaced with GGBS, which is an industrial waste. If concrete mix is replaced with ground granulated blast furnace slag as a partial replacement for Portland cement, it would provide environmental and economical benefits.

GGBS has some pozzolanic properties it leads to. Mechanical Properties Of Concrete Using Steel Slag Aggregate Page | 8 NEED FOR OPTIMIZING AGGREGATE PACKING From the production of concrete, cement is the most expensive material and can account for upto 60% of the total materials Size: KB. The objective of this study is to examine the solidification of toxic elements in tailings by the use of cement and blast furnace slag.

Tailings samples were taken at an Au–Ag mine in Korea. To examine the best mixing ratio of tailings and the mixture of ordinary Portland cement (OPC) and blast furnace slag (SG) of,andthe ratio of tailings and OPC+SG was by: 6.

Use of Blast Furnace Slag Aggregate in Concrete K.G. Hiraskar and Chetan Patil Abstract-The Iron industries produce a huge quantity of blast furnace slag as by–product, which is a non–biodegradable waste material from that only a small percentage of it is used by File Size: 1MB.

slag is a long one. Production of Portland blast-furnace slag cement began inand the Japanese national standard for Portland blast-furnace slag cement (JES 29) was formulated in some of the study has been done in past which summa-rized as: 1.

Sun. Steel Slag - Asphalt Concrete INTRODUCTION Steel slag can be processed into a coarse or fine aggregate material for use in dense- and open-graded hot mix asphalt concrete pavements, (1,2,3) and in cold mix or surface treatment applications.

(4) Proper processing of steel slag and special quality-control procedures are extremely important in selecting steel slag for use in asphalt paving mixes. In this study, compressive fatigue tests were performed in submerged conditions using concrete composed of blast furnace slag or silica fume.

The 2-million-cycle fatigue strength of this submerged concrete improved up to 44 percent of its static strength in water compared to 31 percent for ordinary concrete in water.

The blended binder GU‐GBFS (20% of Portland cement type GU and 80% of ground blast furnace slag – GBFS or slag) was used. The binder content was 5% by dry mass of tailings and aggregates. Table 4 shows the chemical composition of the binding by: 1. Cement Mixtures Containing Copper Tailings as an Additive: Durability Properties Autoclave expansion The impact of copper tailings on CaO, or MgO, or both, induced delayed expansion of pastes was investigated in accordance with the ASTM C specification.

For each mixture, a paste of normal consistency was mixed. The properties and microscopic structure of tailings solidification bodies, the hardening mechanism of the fluorgypsum-based binder material (FBBM) Cited by: 2.

Use of the cementatious properties of ground granulated blast furnace (GGBF) slag was reported as early as GGBF slag has been used in concrete in Japan and Western Europe since the s.

Concrete containing slag is estimated to comprise approximately 20 percent of the hydraulic cement produced in Europe. Blast furnace slag is used File Size: KB. Ground Granule Blast Furnace Slag (GGBS) is a industrial waste material, Which shows cementitious properties.

This paper briefly describes the history of GGBS in. The higher content of calcium oxide in slag results in its being more reactive than PFA and a more effective cement extender when early strength development is required. SMART, R. and VAN HEERDEN, D.

The use of granulated blast furnace slag based binders. Blast furnace slag is used as supplementary cementing material for the production of blended cement and slag cement. Its latently hydraulic properties can be activated by several methods. Most applications employ the use of high pH values in the pore solution (> ) to accelerate the corrosion of the glass network of the by:.

Portland cement (OPC), with a strength class of in accordance with Chinese National Standard GB – [25], and ground blast-furnace slag (GBFS) with a Grade S95 in accordance with Chinese National Standard GB/T– [26] and silica fume (SF).

The chemical composites of the binders are given in Table I.Application of Blast Furnace Slag Sand in Cement Concrete–A Case Study Superplasticizer: Superplasticizer used complied with IS and it was of sulphonated naphthalene formaldehyde base for concretes from grade M25 to MInfluence of copper mine tailings on properties of soda activated ground granulated blast furnace slag mortars and pastes was investigated.

Calcination of copper mine tailings was found to be a method of increasing their pozzolanic activity. Material calcined at °C possessed highest pozzolanic activity.

So obtained material can be used as a partial substitution of ground granulated slag in Author: Łukasz Kotwica, Marcin Chorembała, Ewa Kapeluszna, Piotr Stępień, Jan Deja, Mirja Illikainen, Łukasz.
