“…The maximum size of the particle diameter of all FFs was 0.5 mm. The ball mill used, disintegrator, and the procedure of the preparation of ceramic fillers were thoroughly described in previous publications [ 19 , 21 ]. The granular compositions of all prepared fine and coarse fillers are presented in Table 2 .…”

Our research focused on the influence of fillers obtained from crushed waste materials on the selected properties of concrete composites. The used waste materials were sourced from the production of ceramic tiles, ceramic pots, and sanitary ceramics. We evaluated concretes modified with the addition of 10% (by mass of cement) of different fillers. The properties, including the air content in the fresh concrete mix, consistency, compressive strength, and freeze-thaw resistance were examined. The evaluation of the freeze-thaw resistance was carried out by testing the concrete with the direct method for 150 cycles of freezing and thawing. The characteristics of the concrete porosity structure were assessed using automated digital image analysis. Concretes modified by coarse and fine fillers were characterized by different improvements in the mechanical properties and resistance to cycles of freezing and thawing. Composites with the addition of coarse fillers did not show any significant changes in comparison to the control concrete. An automated digital image analysis of the pore distribution in concrete proved to be an effective tool for the assessment of the freeze–thaw resistance of the concretes in question.

This article presents the results of the research program aimed to analyze the opportunities for using waste ceramic pots for the production of watertight concrete. The mechanically processed crushed ceramic pots were added to the concrete mix in two ways: as a microfiller and as a recycled fine ceramic aggregate. The ceramic meal with a fraction below 0.25 mm was obtained by processing crushed pots using a mill and disintegrator. The pulverized ceramic material was added in 10%, 20%, and 30% of the cement mass. Recycled fine ceramic aggregate with a particle diameter up to 4 mm was created using only industrial mill. The aggregate obtained from pots was used to replace 20%, 30%, and 40% of the sand mass. Altogether, seven different mixes were created. The testing covered following properties: compressive strength, water absorption, and depth of water penetration. Concretes modified with the ceramic meal obtained higher compressive strength, lower water absorption and lower values of depth of water penetration in comparison to reference concrete. Mixes with recycled fine ceramic aggregate were characterized by slightly higher compressive strength in comparison to the reference concrete and similar values of water absorption and depth of water penetration.

“…Probably the most interesting approach to harness crushed red ceramic elements as waste aggregate is associated with utilization of an internal curing process [ 8 ]. It is also possible to recycle other waste materials, such as mortar, concrete, cement, or lime plaster, and use them as micro-fillers or powders that can partially substitute cement [ 9 ]. The most problematic from the recycling perspective is thermal insulation (usually in the form of expanded polystyrene foam (EPS)) glued to bricks by ordinary or highly specialized cement mortar.…”

Concept of Sustainable Demolition Process for Brickwork Buildings with Expanded Polystyrene Foam Insulation Using Mealworms of Tenebrio molitor

The traditional demolition process for brickwork buildings results in a significant volume of mixed debris. The debris consists of ceramic bricks (and other wall elements), mortar, thermal insulation (usually expanded polystyrene or rockwool), smaller steel elements, pieces of wood, and glass. Such mixed debris is difficult to recycle. Separating thermal insulation that is “glued” by cement mortar to brickwork is probably the most difficult and time-consuming task in processing mixed debris. This task can be performed in a very different and fully “automatized” manner using Tenebrio molitor mealworms. The mealworms remove expanded polystyrene from brickwork surfaces and transform it into frass. In the paper, a research program aiming to prove the concept of using the mealworms of Tenebrio molitor for processing mixed debris is presented. The tests were conducted using two models of a three-layered brickwork wall, which is very common in Europe. The proposed approached was successful. Both types of used expanded polystyrene foam (EPS) were fully removed from multilayer wall specimens. The possibilities and limitations of the proposed processing method were discussed and analyzed. The conducted research proved that it is feasible to clean brickwork debris from the EPS using Tenebrio molitor mealworms. Differences in the speed of cleaning process regarding the type of EPS were noted. More research is needed to scale the process, and to find the best method for using frass. By using Tenebrio molitor mealworms, one can make the demolition process much cleaner.
