This study proposes a recovery method for waste leather from tanneries, with high chromium content, by incorporating it into a composite material with cement matrix. The natural aggregates were substituted with CRT (cathode ray tubes) glass waste, with high lead content, originated from televisions and monitors dismantling. The material technological production flow was as follows: grinding skin (two types of skin: black and brown were used), mixing the ingredients after own recipes, pouring the mixture into molds, maturation, demoulding. The new material obtained was submitted to leachability tests to determine, using AAS (Atomic Absorption Spectrometry), the total chromium and lead concentration released from the material. The results showed that Cr and Pb were well retained in the cement matrix. The low levels of total Cr and Pb concentration were recorded at pH = 9-10 and pH = 12, for the composite containing black leather waste and and at pH = 2-3 and pH = 12 for the composite containing brown leather waste. Mechanical tests were also provided to evidence the mechanical properties of the composite. The new composite material obtained may be considered as construction material and can be classified in mortars class because of the size of the used aggregate (CRT glass waste). The objective of this study was to obtain a composite material that can be used as material for construction, in compliance with current standards in construction and environmental legislation. The proposed method for leather waste recovery is viable and environmentally friendly and could bring economic benefits. Keywords: leather, waste, CRT, composite, material.

Gfrp Composite

Silicon Carbide/GFRP reinforced matrix composite and SiC matrix composite has been developed by using hand layup and resin casting methods respectively. The GFRP reinforced polymer composite is made by sandwiching two layers of GFRP in between the SiC material. The resin used for the preparation the samples are epoxy and polyester, for both Sic/GFRP composite and SiC composite. An Arcan fixture with butterfly specimen is used to measure the fracture occurring in various modes of the polymer composite. The objective of the proposed testing method is to determine the variation in the stress value depending on the resin material as well as the influence of GFRP in the strength of SiC polymer composite. Results from the tests are analyzed to show that the polyester resin is better for shear strength, in both Sic/GFRP reinforced and SiC composite material.
