Cement paste Concrete Durability Enthalpy abstract This study investigates the durability of cementitious composites containing microencapsulated phase change materials (PCMs). First, the stability of the PCM's enthalpy of phase change was examined. A reduction of around 25% in the phase change enthalpy was observed, irrespective of PCM dosage and
This case study report focuses on cross-stitching in the lead State of Kansas but also includes information from Missouri, Minnesota, and Utah. The Kansas specifications for cross-stitching are considered to be very effective. Cross-stitching is a
would be to study the feasibility for a group of products involving similar technology in order to set up viable indigenous production units. Based on this consideration, the feasibility studies for various cement based products and a range of roto moulded plastic products has been included in the study. 11.
Jul 25, 2018 Average selling prices of cement increased by 5% YoY, despite continued pricing pressure ACC utilized ~10 mn tonnes of waste derived resources including fly ash and slag CSR expenditure of ` 21.82 crore or 2.33% of average net profit Continued thrust on promotion of premium cement products yielded increase of ~ 20% in sales volume
the factors of capital structure for Cement sector of Pakistan. Used pooled regression model analysis the data and selected 16 firms. The results of study show that the size and profitability inversely related with leverage and tangibility of assets and growth is positively related. Abor, (2005) conducted a study to explore the link among
global cement production in 1969 was the same as that re-ported by the USGS (USGS, DS140, etc.), their estimate of emissions from cement production in 1969 would have been 256MtCO2. In a landmark paper of 1973, Charles Keeling presented a systematic analysis of emissions from fossil fuel com-bustion for 1860–1969 and cement production for 1949–
This study compares the quality of different brands of Ordinary Portland Cement (OPC) available in Bangladesh. The amounts of chemical constituents like SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, insoluble residue (IR), free lime and loss on ignition (LOI) were determined in accordance with British Standard (BS) Specifications. All the results are presented to provide both quantitative and qualitative
This study used 2%, 3%, 5% and 10% cement raw mix waste dust instead of calcite, which is used in a standard wall tile recipe. Another industrial waste, marble dust, was also used as a source of

Feb 20, 2018 Their effective absorption bandwidth reaches to 12.5 GHz, 14.8 GHz and 14.8 GHz, respectively. For pure cement, due to its compact structure and the impedance mismatching between the air space and the sample, most of the incident wave will be reflected at the surface of the sample, which will lead to a poor absorbing property.
Cement accounts for at least 5 percent of anthropogenic emissions of greenhouse gases, and, according to some estimates, this share may be even higher. At the same time, energy-related expenses in the cement sector, mostly on fossil fuels and electricity, account for 30 to 40 percent of the industry’s cash costs. While current energy prices are
In order to increase the sensitivity, frequency bandwidth and longitudinal resolution of the 1-3 cement-based piezoelectric ultrasonic sensor, different metal powder/epoxy resin composite materials were used to make backing layer, and the performances of sensors were evaluated and compared. The results indicated that the increase of the sensitivity and the frequency bandwidth, as well as a
This bandwidth study examines energy consumption and potential energy savings opportunities in U.S. cement manufacturing (North American Industry Classification System (NAICS) code 327310). Industrial, government, and academic data are used to estimate the energy consumed in the cement …
Dec 11, 2017 This bandwidth study examines energy consumption and potential energy savings opportunities in U.S. cement manufacturing. The study relies on multiple sources to estimate the energy used in the production of four cement manufacturing sub-processes, representing 97% of sector-wide energy consumption in 2010.
bandwidth study to analyze the different unit operations used for seawater desalination for municipal (defined here as systems serving more than 10,000 people) systems providing potable water, and provide hypothetical, technology-based estimates of potential energy savings opportunities across the desalination system. The
This bandwidth study examines energy consumption and potential energy savings opportunities in U.S. plastics and rubber products manufacturing (NAICS [North American Industry Classification System] codes 3261 and 3262). Industrial, government, and academic …
This bandwidth study examines energy consumption and potential energy savings opportunities in U.S. aluminum manufacturing for lightweighting applications. Industrial, government, and academic data are used to estimate the energy consumed in five of the most …
