Sustainable approaches for developing concrete and mortar using waste seashell

An insight into the structure, composition and hardness of a biological material: the shell of freshwater mussels

“…[32][33][34][35][36][37][38] While discarded marine shells derived from mussels, oysters, clams and abalones have been characterized as biological material with multiple utility, few efforts have been made from the freshwater mussels. 41,54 Several studies have shown that shells of marine bivalves and gastropods are more worthy as waste with multiple applications in the eld of biodiesel production, 39,40 waste water treatment, 46,47 soil amelioration, [48][49][50] biosorbent for dye and heavy metal, 45,51,52,54,55 llers and alternative to mortars, 56,57 and as an alternative to the bone materials. 32 In order to judge and qualify the shells of freshwater mussels as a biological material with potential for multiple applications in agriculture and industry, characterization of the shell at the physical and chemical levels is a pre-requisite.…”

“…55 The shells of the bivalves are also considered suitable as llers and for the use as a substitute to mortar. 56,57 Owing to the diverse applications ranging from the water purication to the soil amelioration, the shells of mussels, oysters and clams are true aquaculture waste with considerable value to safeguard ecology and mobilize economy.…”

Asphalt is extracted from crude oil, which is a non-renewable resource.…”

Process parameters optimization for eco-friendly high strength sandcrete block using Taguchi method

“…Furthermore, most international standard testing schemes are dedicated largely to the testing of hardened concrete blocks or bricks which does not account for the peculiarities associated with the sandcrete blocks. For instance, BS EN 12390, Part 3 [60], which deals with the testing of hardened concrete, specifies that during the application of load to the hardened concrete blocks, that constant loading rate should be 5 Ç 0:5N=mm 2 :s for concrete blocks with CS less than or equal to 7N=mm 2 , and 10 Ç 0:5N=mm 2 :s for concrete blocks with CS greater than 7N=mm 2 . These constant loading rates specified in the BS EN 12390, Part 3 [60] are high and cannot be favorably utilized for the testing of hardened sandcrete blocks.…”

“…Introduction 1 The soaring cost of Portland cement, an essential construction material that is used principally as binder in cement-based construction, has necessitated the need to find replacement for it either partially or wholly. Replacement of cement assist greatly to drive down the cost of construction as well as to cause a reduction in greenhouse gases generated during its production [1,2,3,4,5,6,7,8]. Several potential low cost materials such as bone powder ash [9], granite sludge [10], ceramic waste powder [11], cement kiln dust [1], slag waste [12], and others [13,14,15,16,17,18]which are otherwise considered as waste materials have been recycled and used as partial replacement of cement in eco-friendly and low cost cement-based construction.…”
