Blended Cements Slag Cement Association

Blended cements can be produced to provide the performance benefits that are also available when slag cement is used as a separate component of the concrete mix. By varying the proportions of the blend, attributes such as sulfate resistance and resistance to alkali silica reaction can be attained with a blended cement.

Blended Cement an overview ScienceDirect Topics

M. Glavind, in Sustainability of Construction Materials, 2009. Blended cement. Blended cements are gaining more and more markets. Blended cements are cements in which part of the clinker is substituted with other materials. Of particular significance throughout the world are granulated slag from the production of pig iron, FA and uncalcined limestone.

Hydration of slag-blended cements ScienceDirect

Oct 01, 2012· Compared with alkali-activated slag, the slag-blended cement hydration process is more complex, due to the coexistence of clinker hydration and slag reaction. One of the principal reasons for the use of slag in blended cements is the reduction of the heat released during the hydration process.

Evaluating Properties of Blended Cements for Concrete

In the present research, cements containing ground granulated blast-furnace slag (GGBFS) and ordinary portland cement (OPC) were defined as blended cements or slag-blended cements. The amounts of slag in the blended cements used were 20%, 25%, and 35%. Class C fly ash (15%) was used with the blended cements. The cements containing fly ash,

Properties and hydration of blended cements with

Prior to the preparation of the blends with cement, the steel slag (size fraction: 0–5 mm) was ground, in a 1 kg laboratory ball mill using steel balls as grinding medium, to a specific surface area of about 3000 cm2/g (according to the Blaine air permeability method) [15]. Then, the blended cements were produced by mixing the slag and the

Durability of slag-blended cement due to U-phase

Cylindrical cement paste or slag-blended cement paste specimens with a water to binder ratio of 0.6 was prepared where the mixing solution was pure water or 13 wt% Na 2SO 4 solution. The mixture was stirred manually until bleeding stopped. The specimens were sealed and cured at 50 8C for 28 days before exposure.
