Abstract. Large amounts of ceramic sanitary-ware waste are generated in both the production process and construction and demolition practices. This waste contains amorphous phases that may react with the Portlandite that originates during Portland cement hydration or with an alkali solution, leading to a low CO 2 -binding material. This study investigated the pozzolanic activity of ceramic sanitary-ware waste, together with its potential to form new binders by alkali activation. For this purpose, raw material was characterized by X-ray diffraction, X-ray fluorescence, particle size distribution, thermogravimetry (TGA) and scanning electron microscopy (SEM). Percentages of ceramic waste of 15 wt.% and 25 wt.%, to replace Portland cement, were used to assess the pozzolanic behavior of this material, and samples were cured at 20ºC for different curing times. Alkali-activated samples, in which Ca(OH) 2 was used as a source of calcium, and NaOH and sodium silicate solutions were utilized as activators, were cured for 7 days at 65ºC. The microstructural evolution of the developed binders was assessed in pastes by SEM and TGA analyses, and mortars were used to evaluate the compressive strength behavior. While some strength gain was observed due to pozzolanic activity, compressive strength values within the 14-36 MPa range were obtained in the alkali-activated mortars in accordance with the activator concentration and the percentage of Ca(OH) 2 addition.

“…Its treatment, to obtain the appropriate forms, is also difficult and expensive. The comparison of high temperature resistance of the mentioned mineral, derived from research [13], to the recycled concrete made of ceramic waste materials showed some resemblance between these materials. A concrete advantage is the ease of forming any shape.…”

“…These are the temperatures at which the materials maintain the invariability of shape, form, and physical state. This value for the heat resistant concrete was adopted in accordance with [13]; no destructive processes were observed at this temperature. It is easy to note that the ability to store the maximum amount of heat in a material's volume, to a very large extent, depends not so much on the material's heat capacity, as on its resistance to high temperatures.…”

“…The recycled aggregate used in the study was prepared on the basis of a post-production waste of sanitary ceramics [13]. Aggregate crushers were used to prepare the aggregate, allowing for the separation of the fine fraction (0-4 mm), which passed through a 4 mm sieve and the coarse fraction (4-8 mm), grains which remained in the 4 mm sieve, but passed through a sieve with a mesh of 8 mm.…”

Abstract:The paper presents the results obtained in the course of a study on the concrete made of aggregate obtained from wastes of sanitary ceramics. Previous examinations proved high in strength and durability of concrete of this type, and it showed a resistance to high temperatures. The material was classified as a fireproof concrete. While searching for the optimal applications of such concrete, a series of examinations and analyses on its thermal energy storage (TES) properties were performed. This paper describes the two-stage experiment on the thermal behavior of the concrete made with sanitary ceramic wastes during cooling processes in comparison to different building materials subjected to the same thermal conditions. On the basis of the thermal, infrared analysis, and suitable calculations, the thermal power and the ability of the composite to store thermal energy was estimated. Finally, it was stated that the concrete made of sanitary ceramic waste aggregate and alumina cement can be recommended as a heat-accumulating material, and in combination with high durability can be used, e.g., for the construction of fireplace bodies.

Summary The residual properties of concrete subjected to elevated temperature are of importance to assess the stability of the structure. This paper investigates the performance of concrete containing white ware ceramic sand exposed to elevated temperature. Concrete mixes containing 0%, 50%, and 100% ceramic sand were prepared. The specimen were exposed to elevated temperatures of 200°C, 500°C, and 800°C for a duration of 60 minutes. Their residual mechanical properties (compressive strength, split tensile strength), ultra sonic pulse velocity, and mass change for different cooling regimes were investigated and compared among specimen. The results showed that incorporation of ceramic sand in concrete mixes improved the resistance against elevated temperature of hardened concrete.
