Coarse aggregate; The coarse aggregate was air dried to obtain saturated surface dry condition to ensure that water cement ratio was not affected. Few characteristics of aggregate that affect the workability and bond between concrete matrixes are shape, texture, gradation and moisture content. In this study crushed aggregates from quarry with ...
aggregate coconut shell as coarse aggregate can be used. Researchers has investigated that glass posses a pozzolana properties due to increase in silica content, so it can be replace fine aggregate to some degree and can improve the strength and also increase the durability of concrete. The chemical compositions of coconut shell taken under study are almost similar to that of ordinary cement ...
shell should be light weight so that‟s why if periwinkle shell should be use in concrete as a coarse aggregate than density of concrete also reduce. That‟s why by using this periwinkle shell as coarse aggregate it‟s make light weight concrete and also get economy. Savings of about % and % can be achieved by adopting % and % periwinkle inclusion for 1:2:4 and 1:3:6 ...
Figure 1: Periwinkle shells . Few of these shells are utilize as coarse aggregate in concrete in areas where there are neither stones nor granite for purposes such as paving of water logged areas, but a large amount of these shells are still disposed off as waste and with disposal already constituting a .
Batching of constituent materials was by weight except for the coarse aggregates (periwinkle shell and sand stone) which were batched by volume. Manual mixing operation was adopted in the laboratory. A total of ninety prototype concrete beams were produced from the given mix ratios. Whereas the first fifteen mix ratios termed the actual mix ratios was used for the formulation of the regression ...
and coarse aggregate in the development of mortar and concrete. PK ash and shell are agrowaste materials from palm oil mills, the disposal of PK ash and shell is an environmental problem of concern. The PK ash has pozzolanic properties that enables it as a partial replacement for cement and also plays an important role in the strength and durability of concrete, its use in concrete will ...
kernel shells and periwinkle shells as coarse aggregate in lightweight concrete. Palm kernel shell was partially a waste in the 1990s and early 2000, more than 350,000 tons were available for sale, especially in concrete work (Mohammed, 2007). The aim of this study is to compare the performance of palm kernel shell concrete and periwinkle shell ...
Keywords: coconut shell, concrete, coarse aggregate, compressive strength, split te nsile strength, flexural strength. 1. INTRODUCTION Concrete is widely used as structural material in the world today. The high demand for concrete in construction drastically reduces the natural stone deposits such as gravel and granite and this has damaged the environment thereby causing ecological imbalance ...
The fine aggregates and coarse aggregates were replaced with lateritic sand and periwinkle shells respectively at 10%, 20%, 30%, 40% and . The mix proportions adopted for this work was 1:1½:3, 1:2:4 and 1:3:7 with water/cement ratio of the results indies that through partial replacement the concrete composed of up to 20% of lateritic sand and periwinkle shell developed a higher ...
the exploratory study of periwinkle shells as coarse aggregate in concrete works. They observed that % and % of the periwinkle shell in replacement for granite was quite satisfactory for compressive strength when using concrete mix ratios of 1:2:4 and 1:3:6 respectively. Otunyo et al. (2013) examined the exploratory study of crushed periwinkle shell as partial replacement for fine ...
BEHAVIOUR OF PERIWINKLE SHELL ASH BLENDED CEMENT CONCRETE IN SULPHURIC ACID ENVIRONMENT I. C. Attah et al Nigerian Journal of Technology, Vol. 37, No. 2, April 2018 317 with PSA on the workability of concrete. The test was conducted in accordance with BS EN 12350: Part 2 [32]
Coarse Aggregate, Fine aggregate, Mineral filler Periwinkle Shell Ash, Bitumen Methods A. CHARACTERIZATION OF ASPHALTIC CONCRETE MATERIALS AND PERIWINKLE SHELLS ASH Tests were carried out on asphaltic concrete materials and periwinkle shells ash (PSA) in order to determine their conformity with acceptable values of some engineering properties, required for the .
product, though a few persons use the shell as coarse aggregate in concrete in places where there are neither stones nor granite for such purposes [3]. There are however, large amount of these shells being disposed of as waste thus constituting environmental problems in places where use carmot be found for them. D. Pure Water Sachet Pure water sachet is a lowdensity polythene which is heavily ...
· Exploratory study of Periwinkle shell as Coarse Aggregate. A total of 300 concrete cubes of size 150 x 150 x 150 mm3 with different percentages by weight of crushed granite to periwinkle shells as coarse aggregate in the order 100:0, 75:25, 50:50, 25:75 and 0:100 were cast, tested and their physical and mechanical properties were ...
Keywords: Periwinkle Shell Ash, Asphalt Concrete, Compressive Strain, Dynamic Modulus, Tensile Strength * ... while the coarse aggregate was allin graded gravel with specific gravity of, and having maximum size of a halfinch (). These aggregates were obtained from the local building materials market at Mile3, Diobu, Port Harcourt, Rivers State, Nigeria. Laboratory tests carried ...
of coconut shell as a coarse aggregate has been discussed based on the results obtained from comprehensive review of literature. We all want that our buildings must be strong and should build with the construction material of reasonable rates. Every construction industry totally relies on cement, sand and aggregates for the production of concrete. Nowadays, most of the researchers are doing ...
However, full substitutes of coarse aggregate with coconut shells also have decreased the compressive strength of concrete [17]. The effects of ground periwinkle shell on the compressive strength of concrete have also been investigated. The work revealed that periwinkle shell concrete had a drop in compressive strength with optimum strength occurring at 5% partial substitution. The addition of ...
