The object of research is the physical and chemical processes of forming the structure and properties of ceramic masses based on local low-melting clay raw materials of the Kyiv region of Ukraine by adjusting the chemical and mineralogical composition and technological regimes. Building ceramic materials are durable, ecological and natural. They provide increased comfort of buildings due to the creation of a favorable temperature and humidity climate of the premises. When using low-melting raw materials in production, there is a need to develop ways and methods to improve the quality of building ceramics. The efficiency of the manufacture of ceramic products largely depends on the processes that occur during drying. This is of crucial importance and affects the quality of finished products and accounts for 10–12 % of the total cost of finished products. Polymineral clay compositions with the addition of natural mineral raw materials are mainly used for the production of construction materials. For effective use of these materials, it is necessary to study their technological properties. Therefore, the question of researching masses based on low-melting clays with high sensitivity to drying, and the use of zeolite-containing mineral rock as an admixture is relevant. This will allow expanding the nomenclature of building ceramics products. Modern physico-chemical and physico-technological methods of research of raw materials and masses based on them during drying were used to solve the task of obtaining ceramic material from local raw materials with the use of a non-deficient natural additive of zeolite-containing rock as an admixture. The conducted studies indicate that the addition of zeolite-containing rock can be used to improve the drying properties of ceramic masses based on low-melting clays. Adding admixture of zeolite-containing rock also increased the compressive strength of finished products, which ensures defect-free transportation of products to other technological operations.

With a purpose of improving mainly the water resistivity and related physical and mechanical property of starch biopolymer, citric acid was used to modify the chemical structure of starch by crosslinking the polymer chains. Corn starch films were produced first dispersing 4% (w/w) starch in water, adding glycerol (36% of the weight of starch) and citric acid (20% of the weight starch) successively allowing them to react at different pH. Water absorption, FTIR, DMA, DSC and SEM tests were done to characterize the thin film samples. Results showed that availability of glycerol is a critical factor for the crosslinking and plasticity property of the film. Samples prepared with citric acid crosslinked starch without the inclusion of glycerol were brittle and has easily disintegrated in water as crystals. The crosslinking reaction done under acidic condition was found more effective than the other reactions. Generally, citric acid has effectively crosslinked corn starch polymer molecules reducing the amount of hydroxyl group in their structure. As a result improvement in the water resistant is observed.

“…The energy used during combustion produces pollution from combustion in the form of CO2 gas, which is harmful to the environment [3]. These bricks can be replaced with environmentally friendly materials, including eggshell waste [4], [5], and plastic waste cut and put into bottles. Amena [6] reported that plastic waste strips and brick waste powder were found to increase the strength qualities of expansive soils.…”

Plastic waste is a serious problem in the community, especially in RW 4,5 and 6 of Notoprajan, Ngampilan, Yogyakarta. The utilization of plastic waste in the region is not yet optimal. This community service activity aims to provide education about plastic waste and train teenagers to make ecobricks. The method used is providing education about the types of plastic waste, the dangers of plastic and the various uses of plastic waste, ecobrick manufacturing. Furthermore, participants will be accompanied to practice directly making ecobricks. The results of this activity were in the form of ecobrick work by the participants. This proves that their understanding and skills have improved with this training.
