Construction waste management involves monitoring, collection, transportation, recycling, and disposal of waste generated during construction activities. Rapidly growing construction activities worldwide generate large amounts of waste material that can pollute the environment if not managed properly. Overproduction, poor handling of materials, inappropriate storage, design alteration, and manufacturing flaws also lead to increasing this waste. Construction waste include broad range of unwanted materials, most of which can be recycled and reused. Common construction waste materials include.

The reuse potential of tire chips as coarse aggregates in pavement concrete was examined in this research by investigating the effects of low- and high-volume tire chips on fresh and hardened concrete properties. One concrete control mixture was designed, which well exceeds CDOT Class P concrete requirements. The coarse aggregate component of the mixture was replaced in 100%, 50%, 30%, 20%, and 10% by volume using tire chips. The fresh concrete properties, compressive strength, flexural strength, splitting strength, permeability, and freeze/thaw durability were tested in the lab to evaluate the potential of including tire chips in concrete paving mixes. The testing results indicate tire chips can be used to replace coarse aggregate in concrete pavement mixtures. Two mixtures with 10% coarse aggregate replaced by tire chips had the best performance. The workability was comparable to the control mixture, and the air content reached 6%. At 28 days of age, the average compressive strength of the two mixtures was significantly less than the control but still exceeded CDOTs specification of 4200 psi; the averaged flexural and splitting tensile strengths were higher than 900 psi and 590 psi respectively. In addition, the two mixtures exhibited moderate resistance to chloride-ion penetration at 28 days of age and high freeze/thaw durability. The rubberized mixtures investigated in this study sustained a much higher deformation than the control mixture when subjected to compressive, flexural, and splitting loadings.

Generators are backup devices that provide temporary AC or DC power using the supplied fuel (gasoline, diesel, or gas). They are used as emergency power source for residential, commercial, and industrial applications. A typical generator is powered by a fuel engine. Portable generators provide AC power for standby non-hardwired applications. Although the low-end models support only a few basic home appliances, the high-end portable generators can provide backup AC power to an entire house. Apart from the residential sector, these generators are widely used in commercial buildings as well as industrial and infrastructure sites. They provide power supply in areas that lack grids.

In this study, we have conducted modeling of the energy demands and supply systems of an actual small-scale housing complex and evaluated the effect of CGS installation from the standpoint of environmental and the economic aspects. Then, we have developed a new CGS operational algorithm that controlled the CGS generator by following the temperature of the heat storage medium in the storage tank and we have demonstrated the advantageous effects of this method. In addition, we have discussed the appropriate heat storage tank capacity for the proposed method.

Excavators are used to unearth, transport, and unload materials with the help of a bucket fitted to a boom. They move on crawlers or wheels. Excavators are versatile heavy construction machines used for below- and above-ground operations, including land leveling, trench digging, and well sinking. The excavator market in Russia is one of the steadily growing construction equipment markets in EMEA and will post a CAGR of 6.54% during the forecast period. The mega events planned to take place in Russia will accelerate market growth.

In this research, twenty batches of concrete with six different mixture proportions were tested with VERIFI to evaluate 1) accuracy and repeatability of VERIFI measurements, 2) ability of VERIFI to adjust slump automatically with water and admixture, and 3) effects on concrete properties when water and admixture are added continuously during transit instead of adding whole at the plant or jobsite. For each batch, concrete was sampled every 30 minutes up to 90 minutes and tested for slump, temperature, air content, unit weight, water content, bleeding (select batches), and rheology (select batches). Cylindrical concrete specimens were cast at 90 minutes and were tested for compressive strength at 3 and 28 d (or 3 and 14 d for IDOT mixes).

Coatings are products used to protect a surface and/or enhance its appearance. Architectural coatings are applied to commercial and residential buildings. They serve to protect a building from elements such as moisture, UV radiation, and microbes. Paints, primers, lacquers, varnishes, and stains are some of the major types of architectural coating products. These products are formulated using various types of resins such as acrylic, alkyds, polyester, and polyurethane. The market may be broadly classified into two major types of coating technologies: solvent-borne and water-borne coatings.
