What is the impact of cement fineness on concrete?
The research on cement fineness has been ongoing since the production of cement, and has been continuously deepened based on the understanding of the properties of cement concrete.
Recently, I heard a new term on a concrete forum called “Grinding Universal Theory”.
Its main viewpoint is that materials such as cement and admixtures need to be ground, and the fineness of cementitious materials is too fine, which causes cracking in concrete.
No matter what material is ground in concrete, it can be used.
Whether the viewpoint is correct or not, it has aroused a lot of curiosity, as if the fineness of cement can be freely controlled.

Analysis of the causes of a concrete explosion accident in a certain school
The male dormitory building of a certain school has a building area of 6600m2 and a frame structure.
The design strength grade of beam and slab concrete is C25, using commercial concrete.
Construction was carried out from March 13, 2010 to August 28, 2010, and the concrete was cured by watering after pouring.
After demoulding, it was found that there were multiple point like bursts on the concrete surface of the beam and slab components, and the number of burst points increased with the age of the concrete.
To ensure the safe use of the building, the construction party commissioned an appraisal agency to conduct testing and appraisal on the concrete of the project, and analyze the cause of concrete cracking.

A concrete company – Technical Disclosure for Autumn Commercial Concrete
Due to strong winds and dry weather, the surface moisture of concrete evaporates quickly.
As a result, the shrinkage of concrete increases, and the probability and penetration depth of concrete shrinkage cracks increase.

How to choose additives correctly for ready mixed concrete enterprises
With the widespread application of concrete admixtures in concrete, they have become an indispensable component in addition to cementitious materials, sand, stone, and water.
The characteristics of concrete admixtures are a wide variety and small dosage, which play an important role in improving the performance of newly mixed and hardened concrete.
The correct selection and use of admixtures is a key link in modern concrete production and quality control, as well as a prerequisite for ensuring the quality of concrete structural engineering.

You must know these questions about concrete slump!
The slump of concrete mainly refers to its plasticizing and pumpability properties.
The factors that affect the slump of concrete mainly include changes in gradation, moisture content, weighing deviation of the scale, dosage of additives, and the temperature of cement, which are easily overlooked.
Slump refers to the workability of concrete, specifically ensuring the normal progress of construction, including its water retention, flowability, and cohesiveness.

A Brief Discussion on Quality Control of Commercial Concrete in the Production Process
Concrete material is the most widely used material in industrial and civil construction, as well as transportation, water conservancy, municipal and other construction projects.
With the development of society, the use of commercial concrete in construction is becoming increasingly widespread, and the requirements for the strength and other performance of concrete itself are also increasing.

Adjustment and Optimization of Concrete Mix Proportion Parameters
The design of concrete production and application involves several important aspects such as concrete raw materials, production, transportation, vibration, and concrete curing.
Only by coordinating these aspects can a suitable mix proportion be formulated.
Optimizing the concrete mix ratio parameters according to different situations is a prerequisite for ensuring the quality of concrete, and it is also the basis and means for adjusting the mix ratio.

How to conduct technical disclosure for winter construction of concrete? Comprehensive guide for winter construction of construction
In the field of construction engineering, with the arrival of winter, the continuous decline in temperature has brought many severe challenges to concrete construction.
Concrete, as a key material for building structures, requires extra caution in its preparation and construction process during winter, as even a slight mistake may lead to quality issues.
Therefore, in order to ensure the quality of the project, we must have a deep understanding and strictly implement the technical points of winter concrete construction.
We hereby submit this detailed technical disclosure and winter construction strategy for the construction and supervision units.

How to reduce concrete shrinkage cracking? Must see for engineers!
Many concrete slabs have just been poured, and soon after, dense, spider like web like cracks appear on the surface, which are often attributed to problems caused by “untimely maintenance”.
