Mineral wool is a type of important material for basic infrastructure development and national economy. It is widely used as insulation material in construction industries. Some high temperature industrial solid waste materials, such as blast furnace slag, cyclone slag and some metal slag, after composition adjusting and reheating, can be directly used to produce mineral wool. The recycle of residual heat in the hot solid wastes can decrease the cost of mineral wool and is beneficial for energy conservation, environmental protection and social sustainable development. The development and technical characteristics of mineral wool production with blast furnace slag, cyclone slag and some non-ferrous metal slag have been analyzed in this paper, and the energy conservation technique in managing high temperature solid waste has been also discussed.

Abstract 3D building printing is a technology for producing 3D models of an object to build any shape or size in layers by using computer software. The development of 3D printing was going to be more famous and commercial in the future to reduce the construction cost and labor demands, sustainability, and to the greenest way. Concrete is the mixture that consists of the ingredients of water, binder (cement) and aggregates (rock, sand, gravel). The productions of Portland cement in construction leads to the emissions of carbon dioxide (CO2) gas into the air. Waste material has been used as cement replacement in this research study to reduce carbon dioxide (CO2) gas emissions. This research study was going to evaluate the viability of concrete for 3D printing and printing emphasizing the impact on potential opportunities of this innovative industry. The behaviour of 3D concrete printing and potential of modified mortar in 3D concrete mix design by using Ground Granulated Blast-Furnace Slag (GGBS) is used to evaluate the potential uses of GGBS in concrete mixture for 3D building printing. This research study involved the review of concrete compressive strength and workability of 3D concrete printing with the control aspect during process manufacturing. The result shows that the mix design of 3D concrete printing with 30% and 40% produced concrete strength of 47.33MPa and 47.67MPa respectively. Furthermore, control aspect requirements of concrete for 3D printing were discussed in the field extrudability, flowability, buildability, strength between layers, aggregates, and water-cement ratio. Throughout this study, the manufactures of 3D building printing materials using environmentally friendly elements can contribute effectively create a sustainable environment automatically.

Background/Objectives:When producing 1 ton of cement, it produces 0.9 tons of carbon dioxide, so it is very important to reduce the use of cement or to find an alternative material.Methods/Statistical analysis: In order to replace cement which is frequently used to make lightweight cured products, blends of blast furnace slag, polysilicon and paper ash were used as binders. In order to stimulate the hardening of blast furnace slag, comparative analysis of characteristics of alkali stimulants was carried out by using KOH and NaOH as alkali stimulants.Findings: In order to improve the foaming performance for the production of lightweight Matrix, we used polysilicon and paper ash as well as blast furnace slag as one of industrial by - product a binder. KOH and NaOH were used as alkali stimulants. The experimental results are as follows.When alkali stimulants are used, the density decreases and the absorption rate increases. It is considered that the use of an alkali stimulant causes air bubbles to occur, resulting in a lower density and an increased absorption rate. The use of NaOH rather than KOH seems to result in better bubble generation. Strength was significantly decreased when alkali stimulants were used, but it was confirmed that the strength of NaOH was increased than that of KOH.Improvements/Applications: As a result of this study, we will fabricate a lightweight matrix that can be used as a prototype by using NaOH according to KS F 2701 standards.

This research project accomplished a study on the technical feasibility of recycling industrial solid waste generated by the discharge of casting sand agglomeration with clay and blast furnace slag. For this, the plan proposed a methodology that initially establishes a process of solid waste encapsulation, by using solidification/stabilization technique on Portland cement matrices, in which the residuals act as small and large aggregates on the composition of concrete, and later it presents the possibility of using this concrete in the manufacture of concrete pieces (concrete blocks) for paving. The results obtained in this research achieved the objective set with great success, regarding the manufacturing of concrete pieces (blocks) for paving urban roads, whenever there is special vehicle traffic or demands capable of producing accentuated abrasion effects (surpassing the 50 MPa required by the regulation), which probes the technical practicability of using waste from sand casting agglomeration with clay and blast furnace slag used in this study, unlocking usage possibilities for construction.
