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.

With the increasing number of vehicle due to the boom of population and rapid modernisation, the management of waste tire is growing problem. Reusing grinded tire rubber in concrete is a green innovation which provide an outlet for reusing waste tire. While providing certain benefits to concrete, incorporation of tire rubber results in significant loss of concrete compressive strength which hinders the potential of rubberised concrete. This paper aims to develop mathematical models on the influence of tire rubber replacement on the compressive strength of concrete using design of experiment (DoE). 33 data sets are gathered from available literature on concrete with waste tire rubber as partial replacement of fine aggregate. Response surface methodology (RSM) model of rubberised concrete compressive strength shows great accuracy with coefficient of determination (R2) of 0.9923 and root-mean-square error (RMSE) of 2.368. Regression analysis on the strength index of rubberised concrete shows that rubberised concrete strength loss can be expressed in an exponential function of percentage of replacement. The strength loss is attributed to morphology of rubber particles and the weak bonds between rubber particles and cement paste. Hence, tire rubber replacement should be done sparingly with proper treatment and control to minimise concrete strength loss.

The suitability of burnt and crushed cow bones (BCCB) as partial replacement for fine aggregate in concrete was studied. The percentages of replacements of fine aggregates of 0, 10, 20, 30, 40 and 50%, respectively of BCCB were tested considering 1: 2: 4 and 1: 11/2 :3 concrete mix ratios. The cow bones were burnt for 50 minutes up to 92oC before being crushed. Ninety-six (96) concrete cubes of 1: 2: 4 mix ratio and ninety-six (96) concrete cubes of 1 : : 3 mix ratio measuring 150x150x150mm were tested for the compressive strength at 7, 14, 21 and 28 days respectively. The research revealed that the BCCB acted as a retarder in the concrete. Water-cement ratio increased with the increase in the percentage of the BCCB. The mixes of 1:2:4 and 1::3 at 28 days curing yielded average compressive strengths in N/mm2 ranging from 16.49 - 24.29 and 18.71 - 29.73, respectively. For the mix ratios of 1:2:4 and 1:: 3 at 28 days curing age,  it was observed that increase in the BCCB content beyond 40 and 50%, respectively resulted to the reduction of the average compressive strength below recommended minimum strength for use of concrete in structural works.http://dx.doi.org/10.4314/njt.v36i3.4

Reactive Powder Concrete (RPC) can be incorporate as a one of the most important and progressive concrete technology. It is a special type of ultra-high strength concrete (UHSC) that’s exclude the coarse aggregate from its constitutive materials. In this research an experimental study had been carried out to investigate the effect of using three types of materials (porcelain aggregate) and others sustainable materials (glass waste and granular activated carbon) as a partial replacement of fine aggregate. Four percentages had considered (0, 10, 15 and 20) % to achieve better understanding for the influence of these materials upon the compressive strength of RPC. Four curing ages had included in this study, these are; 7, 28, 60 and 90 days. The outcomes of the experimental works improved that using porcelain aggregate as a partial replacement had an advanced effect on the compressive strength for all the adopted percentages and for all the studied curing ages. The maximum modification that’s obtained in case of porcelain aggregate was (24.14) % at age (90) days for 20% replacement. Using glass waste caused an increase in the overall values of the compressive strength for all the adopted replacements with less efficient than porcelain to reached (20.69) % at age (90) days for 20% replacement. Regarding the granular activated carbon, only (10%) replacement had a positive influence on the compressive strength to reached (13.16) % while the others caused a reduction in the compressive strength reached to (29.13)% for 20% replacement.

The rapid growth of the population leads to a requirement of infrastructure this leads to scarcity of raw material for construction such as cement and sand. The other hand pollution growing due to thermal power plants, granite polishing unit and plastic waste this need to be removed. This gives an idea of using this compound as a raw material in concrete making. This concept found to effective minimizes disposal of fly, granite power and plastic wastes, and leads towards Green Building Concepts. In this investigation of M25 grade normal concrete is made by cement, sand, and aggregate which is tested and compared by special concrete. The concrete mix is prepared as per 10262 -2019 by adding replacing small amount of Fly ash in place of cement OPC 53 grade, and fine aggregate is prepared by partial replacing with granite powder (0%,10%,20%,30%)and another mix is prepared by adding 0.5 nylon fiber, partial replacement of fine aggregate with granite powder (0%,10%,20%,30%)specimens are casted . The casted specimens are tested for split tensile strength and compressive strength 7, 14 and 28 day’s respectively and these results also compared with each other. I t is observed that compressive strength and split tensile of concrete at 28days of curing show max value when compared with normal concrete. When the percentage of granite powder increases to 30% it shows that a decrease in both split tensile strength of concrete and compressive strength. When we added fiber to the concrete there is an increase in compressive strength and split tensile strength but there is a not much increase in compressive strength but increase in split tensile strength

Aggregate quality is very influential on the strength of the resulting concrete. Both coarse and fine aggregates have various characteristics identified from laboratory test results. This study aims to examine the use of various aggregates for a quality of concrete. The coarse aggregate and the fine aggregate used are obtained from the nearest location to the work to be performed. The quality of the concrete reviewed is K-125, K-175 and K-225. The coarse aggregates used are 1-2 size (in cm), 2-3 size (in cm) crushed aggregate and coral. The fine aggregates used for each of the coarse aggregates are also different. The results showed that the coral aggregate did not meet the gradations of concrete aggregate. While the fine aggregate does not meet the gradation of concrete aggregate for the three types used. The concrete compressive strength test results show the use of coarse aggregates of 2-3 size of crushed and coarse aggregate of corals giving the average compressive strength value required for all planned concrete strength. While concrete using coarse aggregates of rocks of size 1-2 only meet the specified compressive strength, but does not meet the required compressive strength.Key words: Aggregates, concrete, compressive strength
