Suitability of Awka-North (Nigeria) Sedimentary stones

2018-1-18  Aggregates used for concrete whether local or processed have been found to be one of the contributory factors that affect collapse of structures. Over the past decades, the Awka-North iron-stones have been widely used as coarse aggregate in the eastern part of Nigeria for concrete production without proper laboratory test to ascertain

THE PERFORMANCE OF VARIOUS SOURCES OF FINE

Some fine aggregates are produced from by product of quarrying. A uniform sand, consist of coarse, medium or fine aggregates. Fine aggregates used in building construction as 10% or more clay content while a grit sand has low clay content and have greater proportion of large grain sizes (BS 7533: Part 3).

Properties of Some Natural Fine Aggregates in Minna

2013-8-11  Aggregates are generally divided into two groups: Fine and Coarse. Fine aggregate consists of natural or manufactured sand with particles sizes up to 5mm. It consists of inert natural sand conforming to [1]. It does not contain more than a total of 5% by weight of the followings: shale, silt and structurally weak particles [2].

Effect of Local Binary Mixtures of Coarse Aggregates on

ABSTRACT. Aggregates, though considered inert, are the primary components that define concrete’s thermal and elastic properties. It has been shown that factors such as maximum aggregate size, grading, shape, strength, water absorption capacity of coarse aggregates affect the properties of concrete.
