Simplified Environmental Study on Innovative Bridge

Feb 04,  · The aim of this paper is to present a simplified life cycle assessment on an innovative bridge structure, made of wood and ultra high performance concrete, which combines mechanical performance with minimum environmental impact. The environmental analysis was conducted from cradle to grave using the Life Cycle Assessment method. It was restricted to energy release and

of the U.S. Census Bureau at the Chicago Census Research Data Center. Research results and conclusions It uses a rich data set of cement and ready-mixed concrete plants that spans several decades to perform a detailed case study. There is little evidence 7 The aforementioned policy actions against cement and concrete producers in the

Data on different sized particulate matter concentration

Dec 01,  · The presented data (see ) is obtained from a systematic experimental investigation of construction activity (i.e., building a solid concrete block wall).The total average PM concentration produced from the activity is presented in Table 1.The constructed block wall was of size (0.5 × 0.6 m), the total average exposure of different sized particles (i.e., PM10, PM2.5, and PM1) measured by

Analyses of Shrinkage in Concrete | SpringerLink

The necessary fundamental data of basic creep and shape of free shrinkage in time are chosen according to some practical formulations, and for a number of shrinkage data sets and for two different creep functions, the obtained material parameters refer to a typical ordinary concrete and a typical cement

Tensile and flexural performance of concrete members

In the present study, an experimental program was carried out to evaluate the influence of the addition of 10 kg/m 3 of polypropylene (PP) fibers on the tensile and flexural behavior of concrete members internally reinforced with GFRP bars. Mechanical characterization and pullout tests were performed to determine the properties of the constituent materials and to characterize their interface.

Technology and Production Fragmentation: Domestic versus

The data show a strong, positive relationship between plant technology and fragmentation, both in the cross-section and when using panel data to control for plant fixed effects. 2 The estimates from the panel analysis suggest that a firm’s adoption of communication technology between 2002 and 2007 is associated with a 3.1 percentage point

Predicting concrete compressive strength using hybrid

Jul 01,  · Cement and Concrete Research. Volume 145, July FA and BFS have mainly been used to replace part of cement in concrete and the replacement ratio to total binder ranges from about 10% to more than For this purpose, 70% of the whole data (i.e., training data set of 721 instances) were used to train the models, while the remaining data (309

PDF] Thaumasite Sulfate Attack in Cement Mortars Exposed

Although field cases reported the presence of chloride in situations in which concrete suffered from the thaumasite form of sulfate attack (TSA), few laboratory studies have been carried out into the impact of chloride ions on TSA. In fact the literature contains contradictory results with some studies indicating that chloride reduces TSA, while others show the opposite and, moreover, no

Hyperparameter Tuning of Keras Deep ... - Towards Data Science

Before proceeding to the data analysis part, let's get familiar with the different inputs of the concrete dataset. Concrete. Concrete is comprised of three basic components: water, aggregate (rock, sand, or gravel) and cement. Cement acts as a binding agent when mixed with water and aggregates. Compressive Strength

Predicting the compressive strength of self‐compacting

For this purpose, a multi‐laboratory dataset containing 327 SCC samples made with CFFA was employed. The input parameters in the proposed models included the age of the specimen and the amounts of cement, water, CFFA, coarse aggregate, fine aggregate, and superplasticizer, and the only output parameter was the compressive strength of SCC

The Effects of Marble Dust on the Rheological and

Recycling industrial waste materials has become an environmental and economic necessity. The utilization of these materials to develop concrete contributes not only to their disposal, but also to the preservation of the environment. This study attempted to evaluate the properties of sprayed concrete with Marble Dust (MD) as partial replacement of concrete components.

ESSD - Global CO2 emissions from cement production, 1928

Abstract. Global production of cement has grown very rapidly in recent years, and, after fossil fuels and land-use change, it is the third-largest source of anthropogenic emissions of carbon dioxide. The availability of the required data for estimating emissions from global cement production is poor, and it has been recognised that some global estimates are significantly inflated.
