Investigation of Sustainable Geopolymer Composite Using Automatic Identification Technology

Abstract

Geopolymers are materials prepared from alkaline-activated cement without a calcium constituent. They are synthetic materials based on aluminosilicates. The main advantage of these environmentally friendly materials is that they save mineral resources and due to being free of calcium constituents, and only a small amount of CO2 emissions are released into the environment. The circular economy model of sustainable development of new composite materials will ensure the competitiveness of industries, their stable economic growth, and a healthy environment. This paper aims to investigate geopolymer composite materials that were reinforced with a mixture of glass powder from recycled windscreens. The glass 100% circulates in the closed material cycle and can be used again in the manufacturing process without any loss of quality. We are focused on verification of readability of selected automatic identification technology and their usability directly in the manufacturing process of geopolymer composite materials.

Case study: the simulation modelling of selected activity in a warehouse operation

“…It puts pressure on all manufacturing and non-manufacturing companies, using different approaches to effective team building, automation and robotics, and effective management. As the development and implementation of warehousing logistics expanded, companies found that up to 40% of costs in this area could only be saved by efficiently managing and streamlining material flows without the real need to purchase new equipment [21,22]. The development of advanced simulation systems has opened up new possibilities and significantly supported the trend to rationalize warehousing activities, reducing costs and improving business performance [23].…”

“…Each used block represents the part of the process or operation in the simulation model. The blocks have its unique icon and name there expresses its basic usage within the model [22,23]. The created simulation model is the model of discrete simulation created from blocks taken from the ''Discreet Event'' and ''Plotter'' libraries, Fig.…”

“…To put blocks on the modelling area of a particular simulation system is no problem. The problem is to give a logical sequence for the connection of the blocks and set the parameters of the blocks so that they correspond to the real factual system [22]. The ,,Create Trucks entry-Queue 1-Set-Queue 2-Display Value'' blocks, Fig.…”

Modelling as a Tool for the Planning of the Transport System Performance in the Conditions of a Raw Material Mining

“…If the M L values from Table 3 and the P TS traffic performance values from Table 4 obtained by the calculation are compared (the values are bold marked) for the loading sites P1 and P3, they are almost the same. The values are different for place P2, which is due to the form of calculation (1) and (4).…”

“…The essence of sustainable development is the efficient use of natural resources [1]. The mining and processing industry of raw materials contributes to a huge share in the national economy and delivers an invaluable resource for modern civilization [2].…”
