A study conducted by Concrete International Magazine found that lower water-cement ratios resulted in substantially lower creep strains. For example, using a water-cement ratio of 0.35 resulted in a creep strain of only 150 microstrains, compared to 260 and 380 microstrains for water-cement ratios of 0.45 and 0.55, respectively.

Factors Influencing Concrete Workability. As the current author of this chapter, I feel honored to have been chosen to follow in the footsteps of the original authors, I. L. Tyler and Fred Hubbard, who prepared chapters on "Uniformity, Segregation and Bleeding," and "Workability and Plasticity," respectively, which were published in the ...

During the experiment, a certain influencing factor is used as a variable and the other two influencing factors are considered as fixed. The parameters of the CC arch experiment (the wall thickness of the steel tube is 10 mm, the core concrete mark is C40, and the lateral pressure coefficient is 1) in the previous section is adopted as fixed.

The cement process is sole reason why the concrete industry makes up 8% of overall global emissions and 12% of emissions in New Jersey. Global CO2 emissions by category. Cement is made by firing limestone, clay, and other materials in a kiln. CO2 is emitted from the energy used to fire the material, and the chemical reaction produced …

Title: Principles and Factors Influencing High-Strength Concrete Production. Author (s): Leif Berntsson, Satish Chandra, and Tomas Kutti. Publication: …

The parameters that influence the maturity testing using thermocouple are the properties of the cementitious materials, ... The degree of strength formation can depend on many factors which include the curing temperature, age of curing, type of materials used for concrete production, cement types, water-to-cement ratio, etc. It …

jorge santamaria. Structured and unstructured factors affect concrete product. Structured factors are related to concrete production and unstructured factors are related to the construction process.

Arditi et al. and Polat investigated factors affecting the use of prefabricated concrete systems in 1995 and 2008, respectively, in the U.S. They found that contractors and designers communicate ...

Analyzing the stress–strain full curve characteristics of vegetation-type concrete under different influencing factors, an in-depth investigation into its failure mechanism was conducted. It was determined that the design porosity and cement content significantly impact the concrete's performance, particularly in terms of 30-day compressive ...

This analysis includes a full uncertainty quantification involving 951 uncertain variables and factors that would influence the estimates of climate and health damages of concrete production ...

Curing humidity, crew experience and compaction method are the top three factors perceived to affect concrete compressive strength, whereas crew experience, mixing time and compaction method...

This paper gives an overview of various factors that influences the performance of Limestone Calcined Clay Cement (LC3) concrete. Among the various research related to ternary cements, this paper discusses the influential factors, based on the strength and durability aspects. The factors such as the type and purity of kaolinite, …

Proper compaction of concrete can significantly affect its strength and durability. Compaction affects the strength of concrete in two main ways: Increased density: Compaction helps to increase the density of the concrete by removing air voids and filling in the spaces between the particles of aggregate. This, in turn, helps to increase the ...

Bulk weight. The above mention characteristic influences workability, finishability, bleeding, and segregation of fresh concrete effects the strength, shrinkage, density, and durability of hardened concrete. 2. …

The start of curing of geopolymer concrete at elevated temperatures can be delayed at least up to 60 minutes without significant effect on the compressive strength. The test data also show that ...

Given ongoing risk factors, the Portland Cement Association (PCA) has taken a conservative approach to its annual forecast for cement consumption, which Ed Sullivan, senior vice president and ...

Concrete is the key parameter for infrastructural development, while cement plays a vital role as the main ingredient of the respective concrete. Cement production and fossil fuel combustion generate 3.4% of the global carbon dioxide [1]. Therefore, geopolymer (GP) is developed to reduce cement consumption and control the carbon footprint.

Recycling is regarded as an ideal approach to deal with C&D waste. However, the adoption of market for recycled concrete from C&D waste is slow because quality and price are two major factors hindering its wide acceptability. It is observed that the price of recycled concrete is 0–10% higher than that of concrete.

This fresh property directly influence the response of concrete to imposed loads, durability, and even its cost of production; therefore, its investigation is vital for developing functional and sustainable concrete. Various reports are available in the literature on the factors influencing the workability of RAC.

The failure mechanism of lightweight concrete is quite complicated, and it is essential to understand the influencing factor affecting the concrete strength. ...

Globally, concrete is the most widely used material in construction with an annual production exceeding 10 billion t [1]. Concrete has a low unit price, but repairing or replacing damaged material is technically challenging and expensive. Concrete structures may be damaged by a variety of physical, chemical, as well as biological mechanisms.

A. The major factors affecting the time of setting are cement composition, water-cementitious material ratio ( w/cm ), temperature, and admixtures. When cement hydrates faster, the time of setting is reduced. Increases in the w/cm result in increased time of setting. Time of setting decreases as the temperature is increased.

When the sand in production becomes finer, the concrete slump will decrease and the construction become more difficult. On the contrary, when the sand fineness modulus becomes larger, the concrete will have relatively larger slump, worse water retention with the bleeding and … See more
