In Vietnam, calcium carbide residue (CCR) from the acetylene gas factories are not properly treated, causing serious environmental pollution. Based on mineral composition determined by XRD, calcium carbide residue consisted mainly of portlandite (70-72%), calcite (14-16%), hydrocalumite (6-8%), and chemical composition determined by XRF method composed of CaO (53.02%), LOI (39.72%). This calcium carbide residue can be used as a source of hydrated lime, mixed with fly ash, sand, and cement to produce non-calcined bricks and test results show that brick specimens achieved compressive strength 3.0-7.5 MPa, water absorption 12.3-17.5%, density 1.28-1.80kg/cm3. The test bricks satisfied Vietnamese standards for construction bricks.

The main chemical composition of waste brick is silicon dioxide,by means of chemical can stimulate its activity.In this experiment, gypsum, lime sodium hydroxide as activators,through the testing and research about the properties of compressive strength, dry density, water absorption of brick powder foam concrete,analyse the influence of three activators on the properties of foam concrete.The test results show that the:Mixing about 25% lime can guarantee the dry apparent density on the basis of compressive strength increases;Mixing 20% gypsum can make the strength and dry apparent density relatively stable;The incorporation of NaOH make the foam concrete appear quick setting,so it should not be used alone as activator.

Waste tire disposal continues to pose a threat to the environment due to its non-biodegradable nature. Therefore, some means of managing waste tires include grinding them to crumb rubber (CR) sizes and using them as a partial replacement to fine aggregate in concrete. However, the use of CR has a series of advantages, but its major disadvantage is strength reduction. This leads to the utilization of calcium carbide waste (CCW) to mitigate the negative effect of CR in self-compacting concrete (SCC). This study investigates the durability properties of SCC containing CR modified using fly ash and CCW. The durability properties considered are water absorption, acid attack, salt resistance, and elevated temperature of the mixes. The experiment was conducted for mixes with no-fly ash content and their replica mixes containing fly ash to replace 40% of the cement. In the mixes, CR was used to partially replace fine aggregate in proportions of 0%, 10%, and 20% by volume, and CCW was used as a partial replacement to cement at 0%, 5%, and 10% by volume. The results indicate that the mixes containing fly ash had higher resistance to acid (H2SO4) and salt (MgSO4), with up to 23% resistance observed when compared to the mix containing no fly ash. In addition, resistance to acid attack decreased with the increase in the replacement of fine aggregate with CR. The same principle applied to the salt attack scenario, although the rate was more rapid with the acid than the salt. The results obtained from heating indicate that the weight loss was reduced slightly with the increase in CCW, and was increased with the increase in CR and temperature. Similarly, the compressive strength was observed to slightly increase at room temperature (27 °C) and the greatest loss in compressive strength was observed between the temperature of 300 and 400 °C. However, highest water absorption, of 2.83%, was observed in the mix containing 20% CR, and 0% CCW, while the lowest water absorption, of 1.68%, was found in the mix with 0% CR, 40% fly ash, and 10% CCW. In conclusion, fly ash is recommended for concrete structures immersed in water, acid, or salt in sulphate- and magnesium-prone areas; conversely, fly ash and CR reduce the resistance of SCC to heat beyond 200 °C.

Calcium carbide residue is an unutilized by-product. It contains high calcium and can be used to produce cementitious. The variation of Calcium carbide residue used is 0%, 5%, and 15%. This study focused on the reduction of the cement used and lightweight bricks resistance toward the fire condition. Moreover, the tests were carried out by examining the compressive strength before and after lightweight bricks burned, X-ray fluorescence (XRF), Scanning Electron Microscope (SEM), and Fourier-Transform Infrared Spectroscopy (FTIR). The result showed a decrease of compressive strength on 10% and 15% carbide variation. At the combustion temperature of 250 °C, micro-cracking occurred at 0% and 5% carbide specimens, while not only cracking but also spalling and crazing were at the specimens with 10% carbide. The 5% variation of calcium carbide residue can increase the compressive strength and endurance at 250 °C. At the higher temperature, the compressive strength was decreased, and the material was damaged. IR-spectroscopy test results showed that 5% carbide composition achieved the highest compressive strength because the amount of H2O2 used reacts with CaO.

Because the fly ash will produce large amounts of the secondary waste emission after the extraction of aluminum, the utilization of the fly ash residue after the extraction of aluminum has great significance. The autoclaved fly ash bricks studied in this paper use CFB ash residue after extraction of aluminum as the main material, and calcium carbide clay which consists mainly of calcium hydroxide is the waste residua of the production of acetylene gas in the chemical plants. This paper analyzes the chemical composition, the mineral composition and the microstructure of the fly ash residue after extraction of aluminum. In the paper, we also study the law and impacts of compressive strength, flexural strength, frost resistance and water absorption, which are made by calcium carbide clay for the autoclaved fly ash bricks. Experimental results illustrate that calcium carbide clay can significantly improve the compressive strength, the flexural strength and the frost resistance of the coal fly ash autoclaved bricks, and significantly reduce its water absorption.

This paper reports on the potential use of fly ash (FA) and residual rice husk ash (RHA) in producing unfired building bricks (UBB) with the application of densified mixture design algorithm (DMDA) method. In this study, little amount of cement (10–15%) was added into the mixtures as binder substitution. Whereas, unground rice husk ash (URHA), an agricultural by-product, was used as partial aggregate replacement (10–20%) in the mixtures. The UBB of 220×105×60 mm in size were prepared and the hardened properties of the bricks were tested including compressive strength, flexural strength, water absorption and bulk density according to Vietnamese standard. Forming pressure of 35 MPa was applied to form the solid bricks in the mold. The test results show that all brick specimens achieved very good mechanical properties. The compressive strength, flexural strength and water absorption of brick specimens were respectively in range of 16.1–22.1 MPa, 2.8–3.5 MPa and 9.5–14.8% and the other properties of the bricks were well conformed to related Vietnamese standard. It was definitely proved many potential applications of FA and RHA in the production of UBB.

Abstract Sewage waste is a crucial factor in the disposal and also harmful to the environment. The growing demand for waste utilization is construction and demolition waste. This study aims in preparing a brick using construction and demolition waste and sludge waste. The materials such as fly-ash, cement, construction, and demolition waste, and sludge waste are used. The sludge content was added at constant percentage of 30%, 40% and 50% with different proportions such of fly-ash, cement and demolition waste of 3:2:2, 1:3:2, 2:1:2, 2:3:2, 2:3:1, 2:2:1, 2:2:3, 3:2:1, and 1.5:1.5:2 respectively. The physical characteristics such as compressive strength, bulk density, and chemical characterization such as water absorption, pH, and detection of heavy metals were carried out. The test results infer that increase in the content of sludge, the strength decreased. Maximum compressive strength of 14.5 Mpa was achieved for the ratio of 2:3:2 at 30% of sludge. The maximum bulk density was achieved at 30% of sludge. This was attributed due to the presence of organic properties in the brick. Moreover, the water absorption increases with an increase in the percentage of sludge.
