The performance of five composite Portland cements (CPCs) with limestone filler (LF = 10%–25% by mass) and calcined illite clay (CIC elaborated intergrinding was analyzed in paste, mortar, concrete. Hydration studied isothermal calorimetry, bound water, XRD. Flow compressive strength (2 to 90 days) were determined standard mortar. Concretes (w/b 0.45; binder content 350 kg/m3; slump 15 ± 3 cm) ...

Expanding a tool for predicting chloride diffusivity in concrete so it can be used by manufacturers to evaluate the durability of concrete made with blended cements. Part I: Characterizing blended cement materials.

the benefits of using mineral admixtures as a partial replacement of portland cement (pc) are well established in the literature. economic and environmental advantages by reducing co2 emissions are well known. this paper examines the influence of intergrinding and separate grinding on the amount of energy consumption, blaine fineness and particle size distribution (psd) of blended cements, name...

The National Bureau of Standards–National Institutes of Standards and Technology has had an illustrious history of research on the most widely-used, man-made materials of construction, cement and concrete—materials which are often taken for granted, because of their commodity nature and generally successful use in the structures that comprise about 80 % of the Nation’s fixed wealth. The level o...
