Built Constructions Builtconstructions :: Selection of Construction Materials
Building contributes almost 40% of CO2 emissions and is a major contributor to the green house gas (GHG) emissions. Different types of construction materials possess a wide variation of embodied energy and emit CO2 at different magnitudes during its life cycle. Selection of appropriate construction materials can considerably cut down CO2 emissions and make our buildings more sustainable and energy efficient. The study is an attempt to address the issues of sustainable construction and how its selection of construction materials can reduce CO2 emissions and play an important role in reducing the impact of climate change directly or indirectly.. Growing global population and prosperity increase the demand for energy and materials. The growth in demand is approximately exponential, meaning that consumption grows at a rate that is proportional to its current value; for most materials it is between 3% and 6% per year. Exponential growth has a number of consequences. One is that consumption doubles ...

Use of Expanded Polystyrene Technology and Materials Recycling for Building Construction in Kenya :: Science Publishing Group
A growing population in Kenya demands expansion of housing facilities. Traditional burnt bricks, quarry stones, timber, and corrugated iron sheets remain the most commonly used construction materials in Kenya. Expanded Polystyrene (EPS) material derived from the distillation process of crude oil and is 100% recyclable, is an alternative construction material. Use of EPS material reduces the rate at which natural materials such as wood and stones are extracted from the environment, hence promoting sustainable development. EPS buildings are fast to construct, cost saving and have thermal characteristics that are suitable for areas with extreme weather conditions. Structurally, EPS materials have performed well for both low and high-rise buildings of up to ten floors. In Kenya, lack of governing standards and unawareness amongst industry players has hampered adaptability of EPS building materials. This paper discusses the potential of EPS as a construction material in Kenya. It is concluded that Kenya

Patent US6429802 - Determining the condition of a concrete structure using electromagnetic signals - Google Patents
Ground penetrating radar (GPR) is a technique that may be used to image the inside of a structure by collecting the echoes (or reflections) resulting from electromagnetic signals such as, for example, electromagnetic waves of typically high frequency, being radiated into the structure. Typically, the rebars inside of a reinforced concrete structure are strong radar wave reflectors. Locating deteriorated areas within a reinforced concrete structure may be accomplished by analyzing the reflections, particularly the amplitudes of the reflections, from the rebars in the reinforced concrete structure. Furthermore, the extent of deterioration of these located areas may be determined from such analysis. Significantly, the system and method described herein, when applied to determine the extent of deterioration of one or more areas of a reinforced concrete bridge deck, is effective even if a layer of asphalt is laminated to the surface of the reinforced bridge deck. A method and system for determining a

Asbestos in Finishing Cement -Asbestos.net
Since the late 1800s, asbestos has been available to consumers in numerous commercial goods throughout the United States . Because of its low conductivity, non-combustibility, superior insulation qualities and fairly low cost, asbestos was an ideal substance to be used in the production of construction materials for the building of homes, offices and other structures. One such construction material was asbestos finishing cement. Asbestos finishing cement, a mixture of asbestos fibers and material binders, was used to protect and add insulation to many structures of that time. Its even and pliable consistency made it very easy to apply to almost any surface or plane which rendered the compound a useful tool in the construction trade.. In 1977, the Consumer Product Safety Commission (CPSC) prohibited the manufacturing of most construction materials containing at least one percent of asbestos fibers. However, since this ban pertained only to new production of such materials, the existing stock ...

This chemical also minimizes the quantities of cement and water generally required during the construction.
Controlled Release of Construction Chemicals by Encapsulation
Encapsulation and controlled release of active agents is a common practice to improve processing and properties of materials and final products in different industries. Today, a large variety of chemical admixtures are used in construction materials, the performance of which could be improved by a better dosage control. This work presents investigations on the controlled release of encapsulated construction chemicals for future applications in construction materials. The high shear mixing technology was used to produce matrix based encapsulations by agglomeration applied to commercially available construction materials. The agglomeration process was varied by the use of different agitator types, the variation of the agitator speed and the application of additional coating materials. The particle size distribution as well as the particle shape of the produced agglomerates was analyzed by automatic image evolution and scanning electron microscopy. The release behavior of the capsules in aqueous solutions

Biocalcification by halophilic bacteria for remediation of concrete structures in marine environment
2016 Society for Industrial Microbiology and Biotechnology. Microbial carbonate precipitation has emerged as a promising technology for remediation and restoration of concrete structures. Deterioration of reinforced concrete structures in marine environments is a major concern due to chloride-induced corrosion. In the current study, halophilic bacteria Exiguobacterium mexicanum was isolated from sea water and tested for biomineralization potential under different salt stress conditions. The growth, urease and carbonic anhydrase production significantly increased under salt stress conditions. Maximum calcium carbonate precipitation was recorded at 5 % NaCl concentration. Application of E. mexicanum on concrete specimens significantly increased the compressive strength (23.5 %) and reduced water absorption about five times under 5 % salt stress conditions compared to control specimens. SEM and XRD analysis of bacterial-treated concrete specimens confirmed the precipitation of calcite. The present ...
Materials | Free Full-Text | Alkali Release from Aggregates in Long-Service Concrete Structures: Laboratory Test Evaluation and...
This paper proposes a simple model for predicting the development of deleterious expansion from alkali-silica reaction (ASR) in long-service concrete structures. This model is based on some composition and reactivity parameters related to ASR, including the long-term alkali contribution by aggregates to concrete structures. This alkali contribution was estimated by means of a laboratory extraction test, appositely developed in this study in order to maximize the alkali extraction within relatively short testing times and with low leaching solution/aggregate ratios. The proposed test is a modification of the Italian Standard test method UNI 11417-2 (Ente Nazionale Italiano di Normazione) and it consists of subjecting an aggregate sample to leaching with saturated calcium hydroxide solution in a laboratory autoclave at 105 °C. Nine natural ASR-susceptible aggregates (seven sands and two coarse aggregates) were tested and the following optimized test conditions were found: leaching solution/aggregate
