Waterway sand and pit sand are the most normally utilized fine aggregates for concrete creation in many parts of the world. Huge scale extraction of these materials presents genuine ecological risk in numerous parts of the nation. Aside from the ecological danger, there still exists the issue of intense lack in many regions. In this way, substitute material in place of river sand for concrete production should be considered. The paper means to examine the compressive and split tensile qualities of concrete produced using quarry residue, sand, and a blend of sand and quarry dust. The experimentation is absolutely research facility based. A total of 60 concrete cubes of size 150 mm x 150 mm x 150 mm, and 60 cylinders 150 mm in diameter and 300 mm deep, conforming to M50 grade were casted. All the samples were cured and tested with a steady water/concrete proportion of 0.31. Out of the 60 blocks cast, 20 each were made out of natural river sand, quarry dust and an equivalent blend of sand and quarry dust. It was discovered that the compressive strength and split tensile strength of concrete produced using the blend of quarry residue and sand was higher than the compressive qualities of concrete produced using 100% sand and 100% quarry dust.

Nowadays development of infrastructures is becoming number one priority in the world, particularly in the developing countries. So there are great demands within the construction industries for river sand as fine aggregate used in the production of concrete. This has created a very difficult situation; the cost of river sand has increased and also there is great fear from environmentalist and ecologist that in the future there may be scarcity of river sand and the environment and the ecology will be distorted. Hence, the need to find materials which are affordable and available to partially or totally replaced river sand in the production of concrete. This work is focused on the use of quarry dust as a total replacement to river sand in the production of concrete, and comparing the results (compressive strength) to that obtained from conversional concrete made with river sand

This research aimed to utilize Anadara Granosa (Blood clam shell) clamshell waste as a new innovation in concrete technology and to investigate the effect of Anadara Granosa clamshell powder utilization as an aggregate substitution on the concrete compressive strength. The sample size was made of cylinders with a size of 10 cm x 20 cm with variations of clamshell powder 10%, 20% and 30% from the fine aggregate volume then soaked for 28 days as per the method of the Indonesian National Standard. The evaluation results exhibited that the slump value exceeded the slump value of normal concrete with a slump value of 0% = 160 mm, 10% = 165 mm, 20% = 180 mm and 30% = 180 mm. Additionally, it was found that the concrete compressive strength obtained post 28 days were 20.78 Mpa, 21.95 Mpa, 21.17 Mpa and 24.28 Mpa for normal concrete (0%), substitution concrete (10%), substitution concrete (20%) and substitution concrete (30%), respectively. Leading on from these results, it was concluded that the increment of Anadara Granosa clamshell powder substitution led to the increase of concrete compressive strength test.

[ID] Concrete is a very popular building material used in the world of construction services, consisting of a mixture of Portland Cement (PC) or other hydraulic cement, fine aggregates, coarse aggregates and water, with or without using additional materials. The quality of materials such as cement also greatly affects the strength of the concrete after hardening, so the selection of cement quality must be in accordance with the concrete planning regulations in order to obtain optimal results. In Indonesia there are many new cement factories that produce to meet the needs of the community, one of which is the Conch brand cement. So in connection with the above, Conch cement can be examined to compare the value of compressive strength and flexural strength with old cement, namely cement Padang, Tiga Roda, Holcim and Bosowa which are generally always used in concrete planning at this time.The purpose of this study was to determine the comparison of compressive strength and flexural strength of the concrete and the multiplier between cement Padang, Three Wheels and Conch at 28 days of age.

With cylindrical test specimens (150 mm x 300 mm) and size beams (150 mm x 150 mm x 600 mm) three specimens were made for each cement.The maximum concrete compressive strength is found in Padang cement with a compressive strength of 45.86 Mpa, for the minimum compressive strength found in Tiga Roda cement with compressive strength value of 40.19 Mpa and for the compressive strength of cement Conch there is a second with compressive strength value 42.84 Mpa. From the explanation above, the results of 28 days of concrete compressive strength with each cement brand still not reached the planned concrete compressive strength of 38 MPa.

The use of crushed quarry dust as a partial replacement of river sand in concrete production was investigated in this study. This is expedient as quarry dust can be available at some locations with insufficient river sand for construction purposes. The use of quarry dust is also in concrete is also a measure necessary for improvement of concrete strength. River sand was replaced with quarry dust for different mix designs of concrete for 0% to 25% replacement levels with 5% intervals. The physical properties of river sand and quarry dust were tested and reported and the workability as well as compressive strengths of the concrete mixtures were also tested. It was observed that the slump values increased with increase in percentage replacement of sand with quarry dust. The compressive strength of cubes at 28 day curing for control mixture of 1:3:6 at 0% partial replacement of river sand with quarry dust was 12.6N/mm2 but compressive strengths of 21.5 N/mm2 and 26.0 N/mm2 were gotten for 1:2:4 concrete and 1:1.5:3 concrete respectively. As the quarry dust content increased to 25%, the 28day compressive strength increased to 13.58 N/mm2 and 21.57 N/mm2 for the 1:3:6 and 1:2:4 mixes respectively. Compressive strength values decreased to a value of 25.72N/mm2 for the 1:1.5:3 concrete mix. The maximum compressive strength values were reached at 20% quarry dust content at the age of 28 days for the three concrete grades investigated. The increase in compressive strength with inclusion of quarry dust was attributed to the higher specific gravity of quarry dust above river sand. The compressive strength of quarry dust concrete continued to increase with age for all the percentages of quarry dust contents. Quarry dust was recommended as a suitable partial replacement for river bed sand in concrete production.

Abstract Concrete waste as crushed concrete aggregates (CCA) in structural concrete prolongs the technical life of the reference concrete accomplishing closed loop recycling. CCA concrete reaches the reference concrete compressive strength and workability by the densification of CCA and cement paste. Our previous study demonstrates CCA densification by mechanical pre-processing, aggregate quality improvements discerned by increased packing density giving reference concrete strength and workability. This study addresses paste densification with blast furnace slag (GGBS) to replace 30 (wt.%) of Portland cement at reference concrete w/b ratio 0.5 and a lower w/b 0.42. Two CCA replacements are investigated: fine aggregates, CCA50; overall aggregate replacement, CCA100. Compressive strength results show that both CCA50, CCA100 mixes achieve reference values at w/b 0.42, only CCA100 achieves reference value at w/b 0.5 as a climate-optimized concrete. The CCA50 mix-w/b 0.5 reaches reference strength when paste densification by GGBS is combined with CCA densification from mechanical pre-processing of aggregates. The 7-day strength of CCA100 with GGBS increases by 11% by mixing with pre-soaked GGBS. Statistical analysis of CCA100 strength results shows significant improvements with GGBS compared to mechanical pre-processing. Significant improvements are possible in CCA50 mix for a combination of mechanical pre-processed aggregates and GGBS replacement.

Natural river sand is one of the important constituent materials in concrete production while stone dust is a material obtained from crusher plants which is also sometimes being used either partially or fully in replacement of natural river sand in concrete production. Use of stone dust in concrete not only improves the quality of concrete but also conserve the natural river sand. However, due its scarcity and environmental degradation caused resulting from excessive mining of Natural river sand, there is need to investigate an alternative material of the same quality which can replace river sand in concrete production. In the present study, experiments were carried out to study the gradation of aggregates, workability, compressive strength and split tensile strength of concrete made using quarry dust as replacement of fine aggregate at 0, 25, 50, 75, and 100%. Grade M15 of concrete was produced with ordinary Portland cement (OPC) for referral concrete while M25 of concrete was prepared for compressive strength and split tensile strength concrete. Workability and Compressive strength were determined at different replacement level of fine aggregate and optimum replacement level was determined based on compressive strength. Results showed that by replacing 50% of fine aggregate with quarry dust, concrete of maximum compressive strength can be produced as compared to all other replacement levels. The effect of quarry dust on compressive strength and split tensile strength was investigated and from the overall result obtained, it was observed that the compressive strength and split tensile strength increased significantly for all the curing ages from 0% to 50% replacement level of quarry dust. Maximum value obtained for 28day compressive and tensile strength were 25N/mm2 and 2.3N/mm2 respectively and this occurred at 50% replacement.

Concrete waste from building construction can cause problems for the environment [1]. The use of fine aggregates from concrete waste can be a solution. The purpose of this study is to determine the value of aggregate characteristics and the value of concrete compressive strength from the utilization of concrete waste as substitution fine aggregate use the DOE (department of environment) method and referring to standards SNI. This study used 50% and 60% waste mortal substitution on sand. The results showed that the characteristics of fine aggregate and coarse aggregate met the characteristic requirements for fineness modulus sand of 2.65 (Zone 2) while the aggregate was roughly 6.44 (Zone 3). The value of compressive strength with 50% and 60% concrete waste substitution each obtained the value of characteristic compressive strength of 57.24 kg / cm² and 101.03 kg / cm². The value of using mortar waste as fine aggregate substitution gives a positive value to the quality of concrete. This is evidenced increase in the value of 14.89% in concrete waste substitution 60%.
