In reinforced concrete structures, the minimum requirement for the thickness of the steel reinforcement protective layer has always been specified.

However, designers determine the thickness according to design standards, and construction and acceptance determine whether the thickness is qualified by applying the allowable deviation in the acceptance specifications based on the design values.

It seems that there is nothing wrong with this.

However, the “General Code for Concrete Structures” (GB 55008-2021) implemented on April 1, 2022, as a requirement that runs through the entire process, clearly states that “the survey, design, construction, acceptance, maintenance, curing, demolition and other construction activities of engineering construction projects must be strictly implemented throughout the entire process.

” The mandatory requirement for the thickness of the steel reinforcement protective layer is:.

Concrete.

For a first-class highway, the pavement structure form and quantity are shown in the table below.

Water stabilized materials and concrete are commercial water stabilized materials and commercial concrete.

The dry climate and large temperature difference between day and night in autumn bring a series of challenges to concrete construction, such as changes in setting time, early plastic shrinkage, and temperature stress.

Metal Rebar Caps

To ensure the physical quality and long-term durability of concrete engineering during this season, it is necessary to implement refined control throughout the entire process of raw materials, production, construction, and maintenance.

The strength standard value is a value in the overall distribution of cubic compressive strength, and the percentage of strength below this value does not exceed 5%, which means there is a 95% guarantee rate.

Cast In Plate

The strength of concrete is divided into twelve grades: C7.

5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, etc.

Concrete and asphalt are the ground foundation materials for various living, leisure, and sports venues.

Spread Anchor

The requirements and standards for concrete or asphalt foundations vary greatly depending on the purpose of the venue, which determines the safety, durability, user experience, and cost of the venue.

Commercial concrete is greatly affected by various factors during delivery and use, especially in unfavorable conditions such as windy and dry conditions in autumn, low humidity, and large temperature differences between day and night.

Metal Rebar Caps

If effective measures are not taken during construction and maintenance, it may cause quality problems.

Therefore, special attention should be paid to autumn concrete construction.
