Abstract Vegetative porous concrete (VPC) could effectively reduce the adverse impacts of engineering construction on the environment and adapt to the demands of sustainable development. In this article, shale ceramsite was selected as coarse aggregate and Cynodon dactylon was chosen as an experimental plant. Based on the conditions of two …
The raw materials and raw material ratio of the shale slag ceramsite were determined by the composition analysis of the shale slag; Through basic experiments, it is concluded that when the ...
Based on the C60 concrete mix ratio, this study uses lightweight ceramsite or material to replace ordinary coarse aggregates so as to obtain a C40 light …
Accordingly to Riley's ternary phase diagram for the preparation of ceramsite, the optimum composition of the raw materials is 40–79% SiO 2, 10–25% Al 2 O 3, and 13–26% fluxes (-CaO, MgO, Na 2 O, and K 2 O) [36].However, the RM used in this study has low silicon and aluminium contents and a high flux content; hence it is difficult to …
Coal gangue (CG) is a type of industrial solid waste produced by the process of coal excavation and separation 1,2,3.Generally, one ton of CG is discarded for every 10 tons of produced coal 4,5. ...
Through a high-temperature calcination process, shale ceramsite (SC) and shale pottery sand (SPS) can be prepared from shale spoil on an industrial scale [11]. SC is widely considered as a good ...
1. Shale ceramsite contains a large number of pore structures with different sizes and different degrees of connectivity. Lightweight shale ceramsite concrete (LWSCC), which uses shale ceramsite as...
The lightweight aggregate plant is also called clay ceramsite production line, ceramsite sand production line, building ceramsite production line, ceramsite production …
The results showed that the single ceramsite compressive strength, water absorption, bulk density, and porosity of ceramsite sintered at 1180 °C with 1.0% SiC were 2.15 MPa, 2.02%, 490 kg/m 3, and 23.85%, respectively. The major mineralogical compositions were quartz, fayalite, and kyanite, with small amounts of albite-low from …
2.1.1. Artificial Lightweight Shale Ceramsite . Artificial lightweight shale ceramsite produced as shown in Figure 1 was used as the coarse aggregate for shotcrete. The raw materials for producing ALSC included municipal sludge, shale, fly ash, general clay, construction waste, remediation soil, etc.
The composition of municipal sludge ceramsite is complex, and the modification treatment technology is difficult to use, so the modification research of sludge ceramsite is less than that of shale ceramsite, fly ash ceramsite and clay ceramsite (Wang et al., 2020e; Yang et al., 2019b; Wang et al., 2019e). To further improve the …
In this paper, a shell structure ceramsite has been prepared and researched in order to attempt a new method of producing lightweight ceramsite. In the experiment, raw material was made into …
The use of ceramsite to construct filtration systems (e.g., biofilters) is a common method for water treatment. To promote such applications, the development of low-cost, high-performance, and environmentally friendly ceramsites has received increasing attention from scientists, and a critical step in the development is the …
The prediction method of elastic properties for lightweight shale ceramsite concrete (LWSCC) and an inverse method of parameter for each phase were also proposed. Based on a damage constitutive and a 3D mesoscale model, the damage process of LWSCC was analyzed. Results show that the elastic modulus of ITZ is about 0.70 times that of the …
Ceramsite prepared from municipal sludge can be used safely in the field of engineering construction and water treatment (Xu et al., 2010; Chen et al., 2015a, …
The adsorptive removal capacities for TP using anthracite, biological ceramsite, shale and quartz sand were 85.87, 81.44, 59.65, and 55.98 mg/kg, respectively. Phosphorus desorption was also studied to analyze the substrates' adsorption efficiency in wastewater treatment as well as the substrates' ability to be reused for treatment. It was ...
2.2 Experimental Design. Considering that T beams have high flexural and shear resistance (Gulec et al., 2021), the cross section of the test beam is designed as a T-section.A total of 5 simply supported beam members were designed and fabricated in the experiment, including 1 plain concrete beam––C, 2 ceramsite concrete beams––CC1 …
Ceramsite, which contains inorganic components such as Al 2 O 3, SiO 2, Fe 2 O 3, FeO, CaO, MgO, Na 2 O, and K 2 O, has been used as a construction material, for example in cement mortars ...
To develop lightweight high-strength concrete (LWHSC) for offshore structures in a harsh seawater environment, LWHSC with shale and clay ceramsites was designed. LWHSC was experimentally investigated in terms of density, compressive strength, and durability in a coastal environment. Then, its feasibility for offshore …
In order to produce lightweight ceramsite and reduce the use of natural expanded clay, this study aimed to evaluate the feasibility of producing ultra-lightweight …
This experiment used waste foundry sand and ash as the main raw materials; with only a small amount of pore-forming agent and stabilizer added, porous ceramsite with excellent comprehensive performance was obtained at a lower sintering temperature. When the content of waste sand/ash is 75 wt.% and the sintering …
In this paper, a shell structure ceramsite has been prepared and researched in order to attempt a new method of producing lightweight ceramsite.
Some researchers [17] [18] [19][20][21][22][23] have studied the physical and mechanical properties of shale ceramsite concrete including strength, deformation, bond behaviors, microstructure, and ...
To solve the disposal problems of residual sludges, wastewater treatment sludge (WWTS) and drinking-water treatment sludge (DWTS) were tested as components for production of ceramsite. SiO2 and Al2O3 were the major acidic oxides in WWTS and DWTS, so their effect on characteristics of ceramsite was also investigated to optimize …
