30 basic knowledge of concrete, you will definitely need it!
As one of the most fundamental and important materials in modern architecture, concrete’s performance and quality directly affect the safety and service life of buildings.
Here are 30 basic knowledge of concrete, covering aspects such as raw materials, mix proportions, construction, and quality control, to help you better understand and apply concrete in practical work.

The Ministry of Housing and Urban Rural Development has issued new regulations on concrete, which will come into effect immediately! The
Recently, the Jiangsu Provincial Department of Housing and Urban Rural Development issued a notice on strengthening the supervision of concrete quality in housing and municipal engineering, which will be implemented from the date of issuance.

Concrete winter construction, these must be kept in mind
The cold winter has arrived, and concrete construction is facing the challenge of extreme cold and low temperature.
If the anti freezing measures are not in place, it can easily affect the structural strength and durability.
How to ensure the quality of concrete winter construction? The editor who has been engaged in engineering for many years has summarized the following four core points, achieving “no decrease in temperature, no decrease in quality”! I hope it will be helpful for the winter construction project.

Complete guide for winter concrete construction!
According to JGJ/T104-2011 “Winter Construction Regulations for Building Engineering”, winter construction begins when the daily average outdoor temperature remains below 5 ℃ for five consecutive days.
Concrete structure engineering should adopt winter construction measures and take anti freezing measures for sudden temperature drops.

Concrete is always constructed in this way, and whenever there is a problem, it’s the laboratory’s fault?
Whether the strength of concrete occurs and develops regularly, whether surface defects of concrete can be controlled, and whether the durability of concrete can meet the service life are closely related to the construction technology, construction details, and curing of concrete on the construction site.
As for habitual habits, when quality problems arise, they are often pushed to the concrete mixing plant.
According to the following construction method, can we blame the laboratory for poor concrete control?.
What should be paid attention to during winter concrete construction? How to use antifreeze?
According to Chapter 7 of the national standard “Code for Construction and Acceptance of Concrete Structures” (GB50204), based on local temperature data for many years, when the daily average outdoor temperature remains below 5 ℃ for 5 consecutive days, concrete construction should enter the winter season.
At this point, the first day when the temperature remains stable below 5 ℃ for 5 consecutive days is considered the initial day for winter construction.
Similarly, when the temperature rises, the end of winter construction is the day when the temperature remains stable above 5 ℃ for 5 consecutive days.

Concrete buildings that conform to the will of nature – MS Residence/Studio Saransh
The exterior of the residence continues the strong characteristics of brutalism, with the geometric shape of the concrete facade quietly disappearing in the shade.
The square holes and deep slanted window sills on the facade not only enhance the changes in light and shadow, but also soften the visual impression of the building.
