Egg Shell As A Fine Aggregate In Concrete For Sustainable Construction Raji, A. T. ABSTRACT: This work has investigated the potential use of usedegg shell as a concrete material. The usedegg shells were used as fine concrete aggregate. In the laboratory test, conventional fine aggregate was replaced at replacement level.

material. The exact amount of material required will vary according to the nominal size of the aggregate and the particlesize distribution. 2. Recommended sample mass for each aggregate size of processed aggregates (such as sized aggregates for PCC and AC) or composite aggregates (such as AB and CTB)
The particle size distribution, or gradation, of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material. In HMA, gradation helps determine almost every important property including stiffness, stability, durability, permeability, workability, fatigue resistance, frictional resistance and moisture susceptibility (Roberts et al., 1996 [1] ).
pozzolanic materials and thus are suitable for use in the making of concrete [26]. Some physical properties of ceramic waste compared with granite determined by [25] are presented in Table 1. Sudarsana et al. [6] investigated the influence of water absorption of ceramic waste aggregate on strength properties of ceramic aggregate concrete.
In order to help reducing the waste product, the waste paper can become one of a material in producing lightweight concrete. It can be used as an aggregate replacement or as an addition in producing a lightweight concrete. Even though it has been used as building materials for decades, there is still no research result on the use of waste paper
Home / Concrete Technology / CONCRETE MIX DESIGN USING CRUSHED SAND The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.
increased need to find new alternative materials to replace river sand so that excess river erosion is prevented and high strength concrete is obtained at lower cost. Partial or full replacement of natural sand by the other alternative materials like quarry dust, foundry sand and others are being researched from past two decades, in

The materials used for concrete were Binder materials, Fine Aggregate (FA), Coarse Aggregate (CA), Egg Shell Powder ... replacement. Fine aggregate used was Msand from local quarry. Crumb Rubber used in the study to replace fine aggregate.

The methodology used in this study is suitable for objectively evaluating the accuracy of other rapid gradation machines for various applications. ICAR Project 503 was undertaken to study rapid, automated methods of determining the grain size distribution of unbound aggregate products.
reinforcement to the rubber aggregate thereby, increase resistance to deformation under load which subsequently increase the mechanical strength. Purpose of the Study This study has the following purposes 1. To determine the mechanical properties of concrete using rubber chips as partial replacement of coarse aggregate. 2.
Apr 03, 2013· Coarse aggregate is widely known as gravel, and consists of small stones that are generally 10mm (2/5 in) to 20mm (4/5in) in diameter. It is generally used in mixing concrete or to improve drainage. Gravel is also available in a variety of attractive colours and is resilient to vehicles being driven over it, therefore is a very popular material ...
