“…Concrete, which is a typical recycled civil engineering material, is a very useful material for drastically reducing waste, while its constituent material, cement, emits a large amount of CO2 in its manufacturing process. In order to reduce the environmental load and CO2 emission, "Lowcarbon concrete", in which industrial waste and byproducts such as fly ash, blast furnace slag and silica fume instead of cement are used, is noticed [2][3][4][5][6][7].…”

The Paris Agreement was adopted as the international framework against global warming, and the global movement to reduce greenhouse gas emissions is progressing. On the other hand, the final disposal amount will be reduced to 13 million tons in 2025 with considering the situation of waste disposal in Japan. Concrete, which is a typical recycled civil engineering material, is a very useful material for drastically reducing waste, while its constituent material, cement, emits a large amount of CO2 in its manufacturing process. Additionally, due to the Japanese eating habits, a large amount of fishery waste including fish residues and shellfish are discharged. Although these are recycled, only about 30% of them are recycled. In this study, because the hydroxyapatite can contribute to reduction of the amount of cement and the plant growth promoted by phosphorus content, the hydroxyapatite produced from fish bones (Fishbone Powder: FbP), which is a fishery waste, is adopted as an alternative material to cement of planting base porous concrete. In addition, from the viewpoints of various physical properties (porosity, permeability and compressive strength), plant growth conditions and CO2 emission reduction, the potential of recycling FbP as a binder for planting base porous concrete is also examined. As the result, CO2 emission of about 2.6 kg per 1 m 3 of porous concrete can be reduced by using FbP as a binder for planting base porous concrete. Additionally, the plant growth ability is also improved while the compressive strength is maintained above 10 N/mm 2 .

“…The two main elements of cement constitute 70-80 % of cement, so they are the most dominant part in giving cement properties [5]. In order to reduce the negative impact on the environment and CO2 emissions, it is necessary to pay attention to "low-carbon concrete" which uses industrial waste and by-products such as fly ash, blast furnace slag and silica fume as a substitute for cement [6,7,8,9,10].…”

This study aims to determine the effect of using fish bone powder as a substitute for cement and its effect on concrete compressive strength and concrete porosity. Tests for compressive strength of concrete and porosity of concrete were carried out at the age of 28 days using variations of fishbone powder 5%, 10%, 15%, and 20%. The results of testing the compressive strength of concrete at the age of 28 consecutive days were 21,991 MPa, 16,220 MPa, 17,524 MPa, and 12,923 MPa. The largest concrete compressive strength value obtained was a variation of 5% fish bone powder, whereas the porosity values of concrete at 28 days were 11,164%, 12,429%, 11,545%, and 12,764%. Utilization of fish bone waste as a cement substitution can be done in a 5% mixture of fish bone waste. The resulting concrete compressive strength and porosity values are as planned.

“…The huge quantities of the solid waste generated requires disposal which otherwise adversely affects the environment [7,9]. Disposal of this huge solid waste requires a large amount of valuable land which is becoming very scarce in recent days [10]. The utilization of these waste materials in civil engineering offers a great deal of environmental sustainability besides reducing the burden on landfills.…”

Ceramic waste powder (CWP) and rice husk ash (RHA) are one of the highly produced waste materials from tiles industry and rice processing units respectively. Using these materials in concrete as a part replacement for cement offers several advantages like reducing the burden on landfills, reducing the construction cost by replacing costly cement and improvement in performance of concrete etc. due to their mineral composition. In the current study, an effort was made to partly replace the cement with CWP and RHA. Concrete design mix was carried out by using 0, 5, 10, 15 and 20% CWP and varied proportions of RHA were tried on the optimum CWP for cement replacement (0, 5, 10, 15, 20%). Tests were carried out on the fresh and hardened concrete specimens to study the mechanical properties of concrete. Analysis of the test results indicate that 15% CWP yielded best results and 10-15% RHA in combine proportion was found to be the optimum replacement of cement offering higher strength when assessed to the conventional concrete. Maximum compressive strength achieved at 15% CWP and 15% RHA whereas, the flexural strength and split tensile strength were attained at 15% CWP and 10% RHA dosage.
