Tujuan penelitian ini adalah untuk menginvestigasi kekuatan tekan beton agregat recycle (BAR) terhadap pengaruh rendaman air laut. Total tiga puluh benda uji beton berbentuk silinder dengan ukuran (f150 x 300 mm) diproduksi dari dua jenis campuran yang berbeda. Jenis pertama beton agregat normal (BAN) adalah beton normal terdiri atas campuran semen portland, normal agregat kasar (NAK), pasir sungai dan air tawar. Adapun jens kedua (BAR) adalah beton recycle aggregate yang terdiri dari campuran semen Portland, recycle agregat kasar (RAK), pasir sungai dan air tawar. Adapun rencana target kuat tekan beton benda uji adalah sebesar 250 kg/cm2 dengan nilai faktor air semen (fas) sebesar 0.45. Benda uji yang telah dibentuk kemudian dilakukan proses perendaman air laut secara langsung mulai umur 3, 7, 14, 21, dan 28 hari. Tiba saat waktu pengujian, benda uji dikeluarkan dari tempat perawatan dan selanjutnya diangin-anginkan untuk beberapa saat hingga material mengalami kering permukaan. Selanjutnya, pengujian kuat tekan dilakukan dengan menggunakan mesin kompresi tes sesuai prosedur SNI 1947:2011. Hasil pengujian memperlihatkan bahwa Pengaruh rendaman air laut tidak signifikan menurunkan kuat tekan beton BAR setelah membandingkan nilai kuat tekan beton BAN yang melampaui rencana mutu beton.

Sorptivity Test

Reusing concrete is the best choice to diminish the eagerness on mind blowing standard assets and to oblige the total of waste which is engineered in landfills. Reused concrete has been regularly used as an unbound material as a touch of dams, bases, and sub-bases. RAC has in like way been utilized as a piece of the improvement of asphalts and wastes yet in less case as the examination in this field is not the most outrageous utmost of RAC has not yet been investigated. In this investigation the reused total was utilized as supplanting with 20%, 40%, 60% and 80% by substitution of typical aggregate. Standard Ordinary Portland cement was supplanted with 10% of mineral admixture silica fume. Tests were coordinated to choose the mechanical properties and durability properties such us rapid chloride penetrability test and water sorptivity test. The results show that increasing the recycle aggregate percentage above 40% with natural aggregate, small modifications to the mix design may be adopted to secure that comparable property to natural aggregate concrete is attained

Compressive Strength Of Concrete

Marble Industry produces large amount of waste during mining and processing stages. This waste is dumped on to open land which creates a lot of environmental problems We get recycle aggregate from the old dumped structures and buildings. The main objective of this study was utilization of marble, granite and recycled aggregate waste with polypropylene fiber as a replacement for conventional natural coarse aggregates in concrete. Experimental investigations were carried out to examine the feasibility of use of marble, granite and recycled aggregates waste as coarse aggregates in concrete. Conventional natural coarse aggregates was fully replacement by marble in different percentages 0-60% , granite 0-30% and recycle aggregates 0-40% with polypropylene fiber less than 1% by weight. The concrete formulations were prepared with a constant water.
