The worldwide demand for ornamental stones in building construction is motivating the use of their wastes, generated during fabrication, to produce synthetic stones. This work has as its objective to investigate the production of a synthetic ornamental marble (SOM) under vacuum and vibro-compression processing of a polyester matrix composite with addition of marble waste as a filler. Rectangular SOM composite plates were subjected to compression and flexural mechanical tests. Samples were analyzed to obtain the density, water absorption, and microstructure. The SOM composites presented properties within the expected range of an artificial stone, which indicates that the applied process is suitable for production of this type of material.

Residues incorporation into construction building materials is a promising sustainable alternative for the correct disposal of this kind of material. Brazil is one of the largest world producers of ornamental stones. Nevertheless, the disposal of these residues usually is made outside the industry, which contributes to environmental pollution. This work aimed to evaluate the incorporation of residues from the marble industry into ceramic bricks. Specimens of clay ceramic containing 10, 20, 30 and 40 wt.% of marble residue were prepared and fired at 900oC. The evaluation of the ceramic bricks added with marble residue was based on linear shrinkage, water absorption and mechanical resistance. These properties were compared with Brazilian standards. It was concluded that the incorporation of marble residues, with up to 20 wt%, into the ceramic body is technically feasible and positively influences the properties of the material.

In this article, the effectiveness of the bioconsolidation technique applied to degraded structural materials is illustrated as a new method of consolidation and conservation of the existing building heritage in a less invasive way. Satisfactory results have been obtained by an experimental campaign carried out through non-destructive diagnostic tests, static destructive mechanical tests, and microstructural analyses on a series of natural stone material specimens and artificial stone materials before and after the use of bioconsolidants. The consolidated specimens have been tested after three to four weeks after the application of the M3P nutritional solution on each specimen. The effect on the microstructure of this technique has also been observed using scanning electron microscope and optical photomicrograph, the formation of new calcium carbonate crystals promoting the structural consolidation of the materials under examination was observed in all the specimens analyzed.

This research investigated the tensile and water absorption properties of kenaf fibre mat/polyester composites. Treatment using acetylation method has been introduced to improve the properties of product manufactured. The effects of acetylation treatment with three variations of time that were 1, 4 and 24 hours on the kenaf fibre mats were investigated. The MOE of the tensile of treated fibre mat/polyester composite for 1 hour was the highest with value 4589.61 MPa. The tensile strength of treated fibre mat/polyester composite for 4 hours was the highest with value 0.6213 MPa. For water absorption test, the results showed that fibre mat/polyester composite with treatment duration for 1 hour had the lowest water absorption that was 1.23% compared with treatment duration for 4 hours and 24 hours. For overall it can be concluded that the treatment duration of 1 hour was recommended for acetylation method when compared with 4 hours and 24 hours duration treatments. Using acetylation treatment on the kenaf fibre mat/polyester composites was showed improvement on composite and was recommended in short duration of treatment.

Reinforcing Particles

This work deals with studying the effect of reinforcing SiC particles on the mechanical and plastic properties of a metal matrix composite with a matrix of aluminum alloy AlMg6 (the 1560 aluminum alloy according to the Russian State Standard GOST 4784−97). We assess this effect using the results of mechanical tests at the microscale and macroscale levels. The paper analyzes the fracture mechanism at the microlevel under tensile and compressive stress conditions, as well as the type of contact between the composite constituents. The experimental results obtained for the metal matrix composite are compared with analogous experimental data for the AlMg6 alloy and a compacted material made from the AlMg6 alloy (a compacted powder without addition of SiC reinforcing particles). The studied compacted materials were not previously subjected to extrusion. The tests show a decisive influence of the reinforcing particles on the plastic and mechanical properties of the AlMg6/10% SiC metal matrix composite under compression and tension. For example, the addition of silicon carbide increased the initial yield stress of the compacted material by 26% under tensile tests, and the percentage elongation after fracture was increased up to 1.1%, while it amounted to 0.02% for the compacted material without addition of silicon carbide. Under compression, on the contrary, the addition of silicon carbide degraded plastic properties. As a result, the percentage compression before cracking was 28.4% and 57.9% for the compacted materials with and without addition of silicon carbide, respectively.

Viable Method

The incorporation of ornamental stones residues to a polymer resin to produce artificial stone is an alternative to reducing the environmental impacts of inadequate waste disposal; it also represents a technically viable method. The objective of study was to develop an artificial granitic stone (AGS) using 85% in mass of granite agglutinated by 15% epoxy resin, through a vacuum, vibration and compression process. The artificial stone presented superior properties when compared with the natural granite, it had satisfactory mechanical and physical properties, resistant to temperature oscillations, to impact and wear, therefore suitable for applications for flooring subject to instantaneous tension and high-traffic.

ABSTRACTCement based mortars used for historic masonry restoration presented unsatisfactory results, due to their chemical and physico-mechanical incompatibility to original buildings. In the present research, several syntheses of restoration mortars are produced using traditional techniques and materials such as binders (aerial and natural hydraulic lime), pozzolanicadditives (natural and artificial pozzolanas) and aggregates (sand and crushed brick). The technical characteristics of the mortars were determined using mechanical tests (compressive and flexural) and mercury intrusion porosimetry measurements at the time of 1, 3, 9, 15 months of curing. Water absorption measurements were performed at the time of 9 and 15 months curing, in order to evaluate mortars microstructural characteristics, their rate of water absorption and the total percentage of absorbed water. The aerial lime - artificial pozzolana mortar presented the best mechanical and microstructural performance. Hydraulic mortars acquired the maximum of the mechanical strength in 1 month, lime - pozzolana mortars in 3 months while aerial lime mortars continue to gain mechanical strength even in 15 months curing. Furthermore, the use of ceramic aggregates produces lightweight and elastic mortars, compatible to historicones.

Researches in plant fiber composites have been developed with greater frequency during the last years, especially on environmental issues. The opening of the market, especially in the automotive sector, points to the replacement of synthetic additives by natural reinforcements. Characteristics such as low density and abrasiveness, superior mechanical properties and low cost are the most sought in these composites. The aim of this study was to evaluate the behavior of composites based polyester matrix and fiber of the babassu coconut epicarp, at levels of 5, 7.5 and 10% under testing of tensile strength and impact, as well as the morphology by microscopy scanning electron and water absorption. All composites were prepared raw fibers and fiber with treated with alkaline solution of 5% NaOH. As regards the mechanical properties, an increasing of the rigidity of the system was observed, and the kinetics of water absorption increased levels indicated for compounds with high content of fibrous reinforcement. By SEM there was greater interaction between fiber and matrix.
