Durability Phenomenon in Manufactured Sand Concrete: Effects ...
Abstract. Despite several studies focusing on producing sustainable concrete with nonconventional materials there are short-term and long-term lapses in behavior of some of the concretes. This study with a main focus on durability performance explores strength and behavior of manufactured sand concrete containing alcofine and zinc oxide in severe environmental conditions.
Durability of Concrete Using Manufactured Sand as a Complete ...
test and to substantiate the better uses of manufactured sand and basalt fiber to enhance concrete strength and durability properties. Keywords: Basalt fibers Fibro-Reinforced Concrete Durability test manufactured sand Natural Sand Residual Compressive Strength 1. Introduction Concrete is a building material made from a mixture of
Study on Durability Properties of Concrete using Rice Husk ...
As the river sand has the silts which are not finely graded and inorganic materials which affect the Durability of the concrete the replacement is done with the Manufactured Sand also called as the robotic sand. The Manufactured sand is finely graded and it is the best replacement for filling of voids in the cement aggregate.
STRENGTH AND DURABILITY CHARACTERISTICS OF CONCRETE USING ...
Concrete is one of the most common materials used in the construction field. The current area of research in the concrete wasintroducing foundry sand and metakaolin in the ordinary concrete. Generation of waste foundry sand as byproduct of the metal casting industries causes environmental problems because of its proper disposal.
STRENGTH AND DURABILITY PROPERTIES OF HIGH PERFORMANCE ...
substitute of river sand. The mechanical and durability properties of concrete incorporating M-sand is enhanced due to its filler content and interlocking effect between the particles [10-12]. On the contrary the angular shape of the M-Sand particles tends to reduce the workability which can be improved by the use of water reducers and mineral
STRENGTH AND DURABILITY STUDIES ON CONCRETE MADE WITH ...
effect of M-sand on strength and durability properties of concrete. Some key relevant research findings are discussed below. Patel and Pitroda  reported that the MOE reduced in the presence of fly ash as compared to control mix. It was reported that MOE reduced by 53.79% and 46.43% for concrete grades M25 and M40 respectively when the 40% of cement was replaced by the fly ash.
Effect of Manufactured Sand on Durability Properties of Concrete
penetration test shows that chloride ion penetrability is high for concrete with natural sand while it is reduced using manufactured sand. They attribute this due to coarser grain size of manufactured sand resulting in better packing of particles. They suggest that 70% of manufactured sand in concrete is the optimum replacement for
(PDF) Effect of manufactured sand on the durability ...
The results shows that there is an increase in the durability properties up to 70 % level of replacements of sand with manufactured sand as fine aggregate and for 100 % use of manufactured sand...
The Effect of Replacement of Natural Sand by Manufactured ...
Abstract: The natural sand which excavated from river bed is used to produced conventional concrete. Depletion of natural sand cause the environmental problem and hence sand excavating is restricted by government which resulted in shortage and drastically increase in its cost.
