The evolution of alternative aggregate periwinkle shells respectively at 10, 20, 30, 40 materials is believed to be key to promoting research and 100. The mix proportions adopted for this work in low-cost construction materials. A number of was 11 3, 124 and 137 with watercement ratio of 0.65. the results indicates that through ...
Concrete cubes with periwinkle shells alone as coarse aggregate were lighter and of lower compressive strengths compared to those with other periwinkle gravel properties. The 28-day density and compressive strength of periwinkle were 1944 kgm3 and 13.05 Nmm2 respectively. Periwinkle
concrete using periwinkle shell as aggregate. Three mix proportions of 112, 124 and 136 with watercement ratio of 07 were used. The level of percentage replacement of cement with RHA varied with percentage replacement of 0, 30, 40 and 50 adopted in the course of the work. ...
The use of periwinkle shell is beneficial for satisfactory strengths for normal aggregate concrete and for lightweight aggregate concrete, excellent resistance to heat and economy. This approach is sustainable as a means of recycling and will facilitate the actualization of the sustainable development goal Responsible Production and ...
Dec 20, 2018 They reported that the surface of the periwinkle shell aggregate concrete showed signs of minor cracking and spalling between 300 and 400 C. Major cracks were noticed at 400600 C, and smoke was emitted from the concrete samples between 700 and 800 C. At 800 C, heavy smoke was emitted from the samples and the colour of the periwinkle ...
Many researchers have studied the engineering properties of sea shell, crushed sea shell aggregates and seashell ash in the recent past. A. P. Adewuyi and T. Adegoke et al 2008 concluded that the strength of periwinkle shell concrete is determined based on the properties of the shells and various percentage replacements Concrete with 35.4 ...
aggregate from palm kernel shells, Journal of Housing Science 4, pp. 263276. 2 Exploratory Study of Periwinkle Shells as Coarse Aggregates in Concrete Works A. P. Adewuyi and T. Adegoke -ARPN Journal of Engineering and Applied Sciences, December 3 Adewuyi, A. P., Adegoke, T. 2008. Exploratory Study Of Periwinkle Shells As
obtained for the periwinkle aggregate than the palm kernel shell for all ages and concrete mixes. The increase in the compressive strength was more for the perinwinkle than the palm kernel shells. The 124 concrete mix has the highest increase in the compressive strength with age for both aggregates with the periwinkle having the higher values.
periwinkle shell, laterite and cement. The sand was obtained from Otamiri River at Oweri and is free from dirt. Periwinkle shells were as coarse aggregate augment. Laterite was used in partial replacement of the sand. Ordinary Portland cement was used in this study. Twenty five mix ratios were used. Three of them were used as control mixes.
Aug 29, 2017 Coconut shell concrete can be classified under structural lightweight concrete. In this paper reports the exploratory study on the suitability of the periwinkle shells as partial or in concrete works. Physical and mechanical properties of periwinkle shell and
Yang et al. reported that fine aggregates substitution with oyster shell waste yielded satisfactory results for up to 20 substitution rates 33 E.I. Yang, S.T. Yi, and Y.M. Leem, Effect of oyster shell substituted for fine aggregate on concrete characteristics Part I. Fundamental properties , Cement Concr.
Published works have shown a huge potential of using periwinkle shell an aquatic waste products generated from Periwinkles consumption found in many coastal communities worldwide as
Jun 22, 2019 The study of examined the exploratory study of periwinkle shells as coarse aggregate in concrete works. They observed that 35.4 and 42.5 of the periwinkle shell in replacement for granite was quite satisfactory for compressive strength when using concrete mix
Concrete cubes with periwinkle shells alone as coarse aggregate were lighter and of lower compressive strengths compared to those with other periwinkle gravel properties.
periwinkle shells as alternative material to granite chips as coarse aggregate in concrete and concluded that the use of periwinkle shells for concrete would result in low cost housing delivery especially in the riverine areas where they are found as waste. Emiero and Oyedepo 2012 worked on the Investigation on
Jun 30, 2013 Suitability of Periwinkle Shell as Partial Replacement for River . The bulk density of the periwinkle shells was found to be 515 kgm3 while that for river gravel was 1611 kgm3. The aggregate impact values for periwinkle shells and river gravel were Concrete cubes with periwinkle shells alone as coarse aggregate were . The top of the cylinder was levelled off with the tamping rod.
of periwinkle shells as coarse aggregates and reported that the strengths of such concretes were limited by the strength of the shells but satisfactory enough for structural concrete. Studies on different concrete mixes made with periwinkle shells, though lightweight, resulted in compressive strength in excess of 15 Nmm. 2. The modulus of ...
May 29, 2019 Different types of waste materials such as cockle shell , periwinkle shell , date seed , rubber seed , corn cob ,coconut shell , oil palm shell have partially or fully been used to surrogate fine or coarse aggregate in producing lightweight concrete and their properties evaluated in every investigation .
A prescribed mix of 124, cement, fine and coarse aggregates respectively with water cement ratio of 0.56 was adopted. The mix was further adjusted by replacing the coarse granite with periwinkle shell in partial replacement of the coarse aggregate varied at 0, 30, 40, 50 and 100 percentages.
