“…Among them, carbon fiber-reinforced epoxy resins represent a greater amount due to their many applications in key high-tech sectors such as aeronautics and aerospace industries [271]. Carbon-containing inorganic composites are mainly represented by ceramics [272] and cements [273], but their total production is far lower than polymers. In this scenario, biochar plays a minor role, even if its use is going to be consolidated due to production flexibility and its property tuneability [274].…”

Biochar is the solid residue that is recovered after the thermal cracking of biomasses in an oxygen-free atmosphere. Biochar has been used for many years as a soil amendment and in general soil applications. Nonetheless, biochar is far more than a mere soil amendment. In this review, we report all the non-soil applications of biochar including environmental remediation, energy storage, composites, and catalyst production. We provide a general overview of the recent uses of biochar in material science, thus presenting this cheap and waste-derived material as a high value-added and carbonaceous source.

“…It is estimated that in highly developed countries, losses because of corrosion annually amount to about a thousand dollars per capita. In Poland, they are estimated at 6-10 per cent of the gross domestic product (Afzal et al , 2016; Czarnecki, 2010; Dawood and Ramli, 2014; Hoła and Książek, 2009; Vlahovic et al , 2012).…”

“…It seems that an adequately thick, tight protective coating, produced by covering the surface of cement composites with a special polymer sulfur composite (SC; composed of industrial waste sulfur binder and additions – industrial waste fillers), can provide such protection. Thus far, polymer SCs have not been used for this purpose, even though they are known to be resistant to many aggressive water solutions and to be characterized by low absorbability by weight, high surface hydrophobicity and relatively high tangential and normal adhesion to the surface of many materials, including cement composite surfaces (Afzal et al , 2016; Czarnecki, 2010; Dawood and Ramli, 2014; Hoła and Książek, 2009; Vlahovic et al , 2012; Yang et al , 2014; Zhang et al , 2012; Ramli et al , 2013).…”

“…Owing to image analysis, more systematic and more accurate measurements have become possible. Therefore, more objective characterization of concrete from the aspect of material properties is provided (Afzal et al , 2016; Czarnecki, 2010; Dawood and Ramli, 2014; Hoła and Książek, 2009; Książek, 2016a; Vlahovic et al , 2012).…”

Purpose Specific chemical environments step out in the industry objects. Portland cement composites (concrete and mortar) were impregnated by using the special polymerized sulfur and technical soot as a filler (polymer sulfur composite). Sulfur and technical soot were applied as the industrial waste. Portland cement composites were made of the same aggregate, cement and water. The durability of prepared cement composite samples was tested in 5 per cent solution of HCl and 5 per cent solution of H2SO4 as a function of immersion time. The changes in mechanical strength and mass of the samples were periodically measured. Cement composites impregnated with sulfur composite exhibited limited mechanical strength and mass loss, whereas physico-mechanical properties of Portland cement concrete regressed rapidly. The loss in weight of ordinary concrete impregnated with sulfur composite, kept in aqueous solutions of acids, hydroxides, salts and in water for a year was determined using 100 × 100 × 100 mm samples. The same samples were then used in compressive strength tests. Design/methodology/approach Specific chemical environments affect industrial objects.

The loss in weight of ordinary concrete impregnated with sulfur composite, kept in aqueous solutions of acids, hydroxides, salts and in water for a year was determined using 100 × 100 × 100 mm samples. The same samples were then used in compressive strength tests. The image analysis used for surface destruction monitoring, performed by scanning microscopy for the determination of damaged surface area and the original surface area before acid resistance testing, showed similar results. Based on the image analysis results, a model for predicting the degradation of mechanical strength during durability testing was established. The fact that the calculated and experimental strength values were not vastly different proved the validity of the proposed model. A brief summary of new products related to the special sulfur composite is given as follows: impregnation, repair, overlays and precast polymer concrete will be presented. Sulfur composite as a polymer coating impregnation, which has received little attention in recent years, currently has some very interesting applications.
