Therefore this article is an attempt to demystify clay in concrete critically overview the state of the art on this issue and provide a self contained document that can scrutinise existing related data and the various pieces of evidence examine the available test methods for evaluating the existence and effects of clays in cement based materials and
The clay powder was then recombined with the washed aggregates The grain composition of the clay is presented in Fig 2 and and 325 for These results indicate that the incorporation of clay powder into concrete has a negative effect on its freeze thaw resistance Furthermore an additional decline in freeze thaw
DOI / Corpus ID 260856512; Potential of recycled powder from clay Brick sanitary Ware and concrete waste as a cement substitute for Concrete An overview
Conclusion Although waste clay brick powder decreased the compressive strength of cement paste 5% partial cement replacement with waste clay brick powder was established as an optimum percentage
The experimental objective of this study is to examine the possibility of utilizing clay brick waste as partial replacement for Portland cement in concrete The clay brick was finely ground into powder size and after grinding the morphological characterization of the powder materials was carried out using scanning electron microscopy SEM

Concrete is a mixture comprised of cement 10 15 percent Foundry sand can be used as a fine aggregate substitute in concrete Fine aggregates are generally 3/8 inch or smaller in diameter Foundry sand meets two of the critical requirements for concrete aggregates it is uniformly graded and is strong hard and durable Additional Information
Sustainability and reducing environmental damage caused by CO2 emissions have become issues of interest to researchers in the construction sector around the world Reducing the cement content in concrete by partially substituting it with by products or waste falls within this field as the cement industry is responsible for 7% of global CO2 emissions On the
Mix design of concrete with recycled clay brick powder using the orthogonal design method Contra Build Mater 2012; 31 Pg 289 93 [4] Heidari A Hasanpour B 2013 Effects of waste bricks powder of Gachsaran Company as a pozzolanic material in concrete Asian J Civ Eng 14 5 63 [5] Ilhami Demir HasbiYaprak Osman Simsek 2011
Marine clay concrete and glass powder concrete achieved 12% and 9% of reduction respectively For both case studies adopting GGBFS concrete could result in the highest embodied carbon saving
Class G oil well cement OWC waste clay brick powder CBP silica flour SF deionized water and other liquid additives were used in this study Table 1 presented the chemical compositions of raw materials OWC SF and CBP tested by using a X ray fluorescence spectrometer XRF
The inclusion of glass powder in concrete can have an impact on its performance However by using an appropriate amount it is possible to effectively address the issue of cement energy consumption and achieve favorable economic outcomes The slump test and rheological performance test demonstrate that replacing cement with glass powder can
A study of the replacement ability of parched and grounded clay powder in cement matrix was also conducted by Zhu et al A series of specimens with varying percentages of CP and silica fume were made It was found that flexural strength at day 3 and 28 decreased by 27% and 18% respectively when the CP percentage ratio increased from 9% to 27%
Partial replacement of cement with crushed burnt clay brick waste powder CBP could reduce CO 2 emission enhance the conservation of natural resources and decrease the cost of waste disposal sites The aim of this study is to investigate the use of CBP as a partial replacement for cement in the production of cement mortar
Kasami et al 2001 [4] investigated recycled concrete powder by product in the process of producing recycled aggregate It was found that the recycled concrete powder can be used for self compacting concrete without further processing although the dosage of high range water reducer for a given slump flow and in drying shrinkage may increase
This study looked into the use of marble dust powder in concrete with varied percentages of marble dust 0% 5% 10% 15% & 20% replaced by sharp sand in M20 grade concrete mixes while the
When the ratio of cement powder waste concrete powder waste brick powder is 3 5 2 or 3 6 1 the 28 d compressive strength of the stone body is more than 2 MPa meeting the filling requirements
C&D waste mainly consists of concrete brick glass ceramic steel plastic and wood waste; the proportion of concrete and brick waste in C&D waste is more than 80% and the other main components of C&D waste such as glass and steel waste have a specific recycling path [[36] [37] [38]] Therefore improving the reclamation efficiency of concrete and brick
