Effect of ZSM-5 waste dosage on the properties of autoclaved aerated concrete

Waste Originating from the Cleaning of Flue Gases from the Combustion of Industrial Wastes as a Lime Partial Replacement in Autoclaved Aerated Concrete

“…The SEM image illustrates the needle-like 1.1 nm tobermorite crystals in the reference sample ( Figure 5 a), plate-like 1.1 nm tobermorite crystals in sample with raw waste ( Figure 5 b), and lath-like in sample with calcined waste ( Figure 5 c). The literature review demonstrates that the addition of some industrial wastes can significantly change not only the properties of ACC but also the morphology of calcium silicate hydrates, especially 1.1 nm tobermorite [ 9 , 15 , 55 ]. In recent years, many studies investigated the influence of different types of industrial waste on the synthesis and morphology of 1.1 nm tobermorite [ 56 , 57 , 58 , 59 ].…”

“…Current trends in the construction and the production of building materials aim to reduce the consumption of energy and natural resources in all production processes. Although AAC production technology is characterized by relatively low consumption of raw materials and energy, research is being carried out to replace traditionally used raw materials with industrial wastes [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ].…”

“…According to literature data, utilization of industrial wastes in AAC production allows modifying the properties of AAC [ 14 , 15 , 16 ]. Generally, wastes are considered as a partial replacement for cement or quartz sand.…”

“…Sodium carbonate activated slag [ 17 ], bottom ash [ 18 ], granulated slag, and metakaolin [ 14 ] have been used as cement replacement in autoclaved aerated concrete. However, although many studies [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ] in recent years have concentrated on the recycling of different types of byproducts or residues in AAC technology, fewer reports [ 11 , 19 ] are found about using calcareous wastes to replace lime in the production of AAC. Hauser et al [ 19 ] studied the influence of fly ash from the cellulose industry used as calcareous material on the AAC properties.…”

Image Analysis Technology in the Detection of Particle Size Distribution and the Activity Effect of Low‐Silicon Copper Tailings

“…Firstly, the input layer reads the pixel matrix of the input image and outputs to a convolutional layer with multiple feature surfaces. There are multiple neurons for each feature surface, and the input of each neuron node is the convolution block of the previous network, and using the convolution block in the convolution layer can extract the depth information of the image and obtain higher-dimensional feature information [17]. The convolutional layer is to perform a convolution operation on the input original image to obtain the underlying features contained in the image.…”
