Aggregate occupies most of the volume of the concrete. It is the stuff that the cement paste coats and binds together. The composition, shape, and size of aggregate all have significant impact on the workability, durability, strength, weight and shrinkage of concrete. In this paper analysis of properties of concrete using clay soil aggregates as course aggregate in concrete, transmitting...
Aggregate in concrete acts as structural filler, these place a crucial than simple statement implies it is the material that the cement paste coats and blind together. Now a day’s using river sand is prohibited by government, as these cause soil erosion. In this paper analysis of properties of concrete using manufacture sand as course aggregate is studied and verified the strength of concrete and...
The importation of refractory materials is one of the biggest challenges industries faced in third world countries, of which Nigerian is one of them. The addition of palm bunch ash to clay in the production of clay bricks is one of the ways refractory materials are produced. The clay used here was Nsu clay. This work looked at the compressive strength of refractory bricks which is one of the...
Increase in population results in increase in usage of materials which cause much pollution to environmental surroundings if not disposed properly. Replacement of costlier building material by disposable waste material is one of best engineering practice in construction. In this paper replacement of cement using silica fume is done up to 20% and replacement of fine aggregate using glass powder is...
This paper present the study of various strength such as compressive strength, split tensile strength and flexural strength during 7 and 28 day. It is construct the specimens size 15cm X 15cm X 15cm for testing purpose which depend upon the size of aggregate. Test results are indicated that strength performance of concrete well as in durability aspect are improved using of Silica fume
