Given that the production of high quality RA requires several processing steps, which takes a lot of time and money, understanding the relationship between RA quality and concrete properties can promote efficient utilization of RA. Therefore, this study classifies the quality ...

However, absorption shows a clear dependence on both factors. The adhered mortar has a high absorption, so if concretes have a high amount of recycled aggregates and the quality of the recycled aggregates is low, absorption will increase, exceeding values found in conventional concrete by almost 50%.

High-quality utilization of land resources (HULR) is critical to the security of land ecosystem and sustainable socioeconomic development.To promote HULR, we explored the spatiotemporal differences and influencing factors of HULR in the Yellow River Basin (an important ecological barrier in China) by using entropy method, spatial panel regression …

The results indicated the possibility to produce a high-quality RA, containing more than 99.5% mass of concrete, with adequate properties to …

The study was conducted to factors influencing quality honey production: a case of honey care Africa in Trans Nzoia East Sub County. A descriptive research design will be used in this study. Simple random sampling technique was used to select respondents from the beekeepers. The sample size of 90 will be selected.

The use of recycled aggregates (RA) to replace natural aggregates (NA) in new concrete production has been pointed out as one of the main strategies to close the loop of construction materials. However, producing RA with properties similar to those of NA has been challenging, since current recycling methods struggle to remove contaminants like ceramics …

Factors that control concrete strength, aggregates, cement, and superplasticizers are discussed. Ways of achieving low porosity in cement paste are noted, and laboratory tests are described that have applied the priciples to obtain the maximum possible strength with normal packing on a vibrating table. The results show that it is possible to make mortar and concrete with …

Economic growth increases as functions of aggregate production increase due to technological, human capital, knowledge, and social infrastructure changes. Marginal output is positive due to an increase in the marginal input, i.e., natural resources, land, and labor. Total factor productivity shows output increasing due to technological changes.

The most important aspect of this research lies in the wide range of factors whose influence has been analyzed, including the type of aggregate, the percentage of replacement, the type of sieve curve, the declassified content, the strength of concrete and workability of concrete and the replacement criteria.

Equipment, number of crushing, and technologies for producing RA from concrete waste are factors directly related to the RA quality [58], [59]. Seemingly, the most widely used method in RA production is multiple crushing using crushers based on friction, impact and compression forces and so on.

6.3 Factors Affecting the Quality of the Recycled Aggregate 6.3.1 Influence of the Production Process To obtain recycled aggregate properties suitable for use in higher value applications, operations should be put in place to [ 7 ]: Restrict the type of CDEW that is used.

Ultimately, short run aggregate supply is affected by the change in unit costs of production, that is the cost of producing on unit of good or service in an economy. Productivity - the level of labour, capital and MultiFactor productivity (see the productivity section for more information). Higher level of productivity means goods and services ...

Aggregates are used in concrete to provide economy in the cost of concrete. Aggregates act as filler only. These do not react with cement and water. But there are properties or characteristics of aggregate which influence the properties of resulting concrete mix. These are as follow. Composition. Size & Shape.

The aggregate giving desired quality of concrete with least overall expense (transport + processing + cement required) is the best choice. Types of Aggregate Sources Two types of aggregate sources as listed earlier are described here. 1. Sources of Artificial Aggregates Commonly used artificial aggregates are: Clean broken bricks – brick bats

The results show that it is possible to make mortar and concrete with exceptionally high strength using traditional procedures and the principles discussed. Cement type, amount of silica fume, gap grading of aggregates, size and quality of aggregates, and water-to-binder ratio are major factors that determine concrete strength.

The Aggregate Production Function is the function that shows a technical relationship between aggregate inputs and aggregate outputs. It is a mathematical model that economists use to illustrate the change in productivity because of the changes in factors of production. It helps an economy to produce its potential level of output.
