Effects of Ground Granulated Blast Furnace Slag in Portland .

2001 by slag cement manufacturers and the Slag Cement Association, the American Concrete Institute officially reviewed and changed the terminology from GGBFS to slag cement ACI Committee 233, 2004. The term slag cement will be used throughout this paper when referring to finelyground granulated blastfurnace slag.

Slag Cement Questions Slag Cement Association

Slag cement concrete sometimes turns green for a short period of time due to the oxidation state of sulfide sulphur compounds during portland/slag cement hydration. This is normally a temporary condition and the concrete, upon exposure to air and sunlight, will ultimately become lighter than 100 portland cement concrete.

Slag Cement Benefits and Use in Concrete Slag Cement News

Slag cement is commonly found in readymixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products. While there are many applications and benefits of slag cement, a few are highlighted below and detailed information sheets are located here.

Slag Cement an overview ScienceDirect Topics

The setting time of concrete containing slag cement is commonly retarded. The extent of the delay is influenced by several factors such as the curing temperature, slag cement content, watertocementitious material ratio, characteristics of the Portland cement, and use of chemical admixtures.

Engineering Seminars: SLAG CEMENT

Concrete containing slag cement in excess of 25 replacement dosage generally has noticeably slower set times than ordinary Portland cement concrete. Time of set is related to the percentage of slag cement used in the mix, the temperature of the concrete, and the ambient temperature.

To study the effect of replacement of cement by different pozzolanic material on setting characteristics of concrete in 350 kg/cum and 450 kg/cum cementitious content concrete mixes, the initial and final setting time are determined. For fly ash mixes normally it is expected that use of fly ash will retard the setting time of concrete.

Choosing the Right Blast Media for Abrasive Blasting

A fine abrasive will give you more impacts per volume. The more particles in the stream, the more work is accomplished in the same time. When blasting concrete or wood, you dont need a hard, expensive abrasive, or a coarse particle: crushed glass makes an excellent, inexpensive choice for work on relatively soft surfaces.
