Abstract The use of industrial waste has raised great interest regarding its potential of contributing both to the reduction of costs and to sustainable development. In this context, there has been an increasingly high number of studies addressing the use of alternative materials in the construction industry, especially when considering the difficulty in obtaining building materials near urban centers, which results in an increase in the final price due to transportation costs. This research has characterized and evaluated the use of crushed marble waste to replace natural sand in the production of mortar. Many admixtures of mortar were subject to research regarding their physical and mechanical properties. It has been concluded that mortars produced with sand made of crushed marble waste have improved mechanical properties when compared to traditional mortar.

Quarry Dust

In the view of the expeditious growth of infrastructure around the globe, there is an acute shortage of building materials and also a very stern problem of the disposal of the remaining and continuously generating waste. The demand of natural sand in the construction industry also has magnificently increased resulting in the rapid depletion of the river beds which are the natural sources of sand. Acute shortage of good quality of sand has resulted in to considerable increase in its price ultimately affecting the construction cost. Thus there is a severe need to identify a suitable substitute of sand which is eco-friendly and can be used effectively in construction practices mainly in concrete which requires sand as fine aggregates. An attempt is required to investigate use of some alternative materials to save precious natural resources. The current study focuses on determining suitability of using quarry dust, which is a waste product from quarry, as fine aggregates in traditional concrete. During the tenure of the study, some physical and engineering properties of quarry dust and sand were determined and compared. The compressive strength of concrete was determined after replacing sand with quarry dust in various ratios. The results of the study showed encouraging results for replacement of 50% of sand with quarry dust.

In the current construction industry, great importance is given to the usage of thermally insulating building materials. One of the many such materials can be a cement foam or foam concrete, a mixture of cement mortar and technical foam. This material can be, due to its consistency right after mixing, applied to uneven horizontal surfaces where usage of conventional thermal board insulation materials would be complicated. This paper discusses the methodology of testing of the physical and mechanical properties of foaming additives such as strength, density, foaming number and half-separability of technical foams. Then this methodology was subsequently verified on the five commonly used foaming additives in the Czech Republic.

The main directions of mining and industrial wastes’ utilization are the production of building materials, their use in the construction industry without additional processing, and also the production of metals from metal-containing raw materials. It should be noted that current waste is preferable for the production of building materials, since they preserve the primary physical and mechanical properties and chemical composition and, moreover, can reach the consumer bypassing all other steps that are mandatory for waste consolidated (transportation, storage, etc.). For the production of building materials, not less than 30% of overburden and refinement tailings are suitable, almost all metallurgical and fuel slags, waste products of fertilizers and building materials. Even larger amounts of waste can be used for various laying and burial works (construction of road bases and dams, filling of worked out areas, leveling of the relief).

Present scenario of construction industry is facing problems of organizations of by-product materials like disposal and ground water contamination etc. that are producing naturally in the process of converting one form to other. Scientific experts are trying to create new building materials from these by-product materials that will fit in current situations to avoid damage to society and environment. The addition of these by-product materials to make new building materials makes the environment stable and also produces the durable building products. Aerated concrete is one which uses some of these by-products like fly ash, GGBS etc. and reduces the use of natural sand and cement with enhanced mechanical properties like compressive and tensile strength. As aerated is concrete is poor in flexural strength to improve this property steel fibres are used in proportion This paper mainly focuses on the mechanical properties of aerated concrete like compressive, tensile and pull-out strength with and without addition of steel fibres. After addition of fibres mechanical properties are enhanced up to certain extant.

This study deals with determination of the properties of the fine recycled aggregate (FRA) concrete with partial replacement of natural sand in concrete mixtures. The FRA was obtained from concrete waste and crushed on fraction 0 – 4 mm by laboratory jaw crusher. The geometrical and physical properties of natural sand and the FRA were tested. The main goal of this study is evaluation of the basic physical and mechanical properties of the concrete with partial natural sand replacement by the FRA such as workability, water absorption capacity, compressive strength and flexural strength. A total four concrete mixtures were prepared. The first concrete mixture was prepared only with natural sand, did not include the FRA. In other concrete mixtures, natural sand was replaced by the FRA in various replacement ratios (40 %, 50 %, and 60 %). All concrete mixtures were designated with the same parameters for clear comparison. The workability of fresh concrete mixtures and physical and mechanical properties of hardened concrete were tested.

Pumice, cements (CEM I- and CEM II-type), waste fly and bottom ashes (IFA, GBA, and BBA) supplied from international companies were used to produce lightweight building materials, and physical-mechanical properties of these materials were determined. Axial compressive strength (ACS) values were found above the standards of 4 and 8 MPa (Bims Concrete (BC) 40 and 80 kgf/cm2 class) for cemented (CEM I) pumice-based samples. On the contrary, the ACS values of the pumice-based cemented (CEM II) samples could not be reached to these standards. Best ACS results (compatible with BC80) from these cemented lightweight material samples produced with the ashes were found in 50% mixing ratio as 10.6, 13.2, and 20.5 MPa for BBA + CEM I, GBA + CEM II, and IFA + CEM I, respectively, and produced with pumice were found as 8.4 MPa (same value) for GBA + pumice + CEM II (in 25% mixing ratio), BBA + pumice + CEM I (in 100% mixing ratio), and pumice + IFA + CEM I (in 100% mixing ratio), respectively. According to the results, cemented ash-based lightweight building material produced with and without pumice could widely be used for constructive purposes. As a result of this study, an important input to the ecosystem has been provided using waste ashes, whose storage constitutes a problem.

Plant Fibers

Building materials based on renewable resources such as plant fibers are increasingly needed, especially if the plant is local and easily accessible. One such plant is the Spanish broom, a typical shrub of the Mediterranean region. In this work, Spanish broom fibers were used for the first time to reinforce concrete. Four mixtures were made: a reference mixture and three mixtures reinforced with 3 cm long fibers, in the amount of 0.5% of the total volume. Cement CEM I 42.5R, crushed limestone aggregate (D = 16 mm), and tap water were used for all the mixtures and in equal quantities. Four mortar mixtures were also made: standard mortar and 3 fiber-reinforced mortars. The mortar is reinforced with fibers of the same length and quantity as the concrete. The fibers were obtained by maceration of Spanish broom in solutions of 8%, 10%, and 15% NaOH. The quality and mechanical properties of the cellulose fibers depend on the geographical and climatic conditions and the fiber extraction procedures so the aim of this study was to evaluate the influence of different chemical pre-treatments of the fibers on the mechanical properties of the concrete. The properties of the fresh mix were determined using the flow method. Hardened concrete was tested for compressive and flexural strength and dynamic modulus of elasticity. Compressive and flexural strengths were determined on cement mortars. The results obtained on concrete were compared with those obtained on the mortar. It was concluded that the quality of composite materials is more influenced by the quality of the placement than by fiber treatment.
