How to control concrete for different seasons?
The temperature difference between day and night is large, with less rainfall and higher wind speeds, generally ranging from level 4 to level 5; The air is dry and the humidity is low (generally<30%).
These will cause frequent drying shrinkage, air drying cracks, or a series of other problems in concrete.
.
Can the strength of the specimen be directly used as the basis for defining the quality of concrete?
(1) The GB/T 50107-2010 “Concrete Strength Testing Standard” defines concrete strength as the mechanical properties of concrete, which characterize its ability to resist external forces.
The concrete strength referred to in this standard refers to the compressive strength of concrete cubes.

Analysis on the causes and prevention measures of pipe blockage in pumping concrete
The impact of admixtures on concrete should also be considered.
Salted water reducers can react chemically with hard gypsum in cement, causing false setting and pipe blockage.
Moreover, the amount added can cause concrete segregation and bleeding.
Even when antifreeze is used at high temperatures, it can cause false condensation and blockage of pipes.
So when using additives, it is important to carefully read the instructions, applicable temperature, conditions, and objects, and strictly control the dosage ratio, otherwise it may have counterproductive effects.

Draft for Comments on the Revision of Concrete Quality Control Standards – August 2026
According to the Notice of the Ministry of Housing and Urban Rural Development on Issuing the Compilation of Engineering Construction Standards and Related Work Plans for 2024 (Jian Biao Han [2024] No.
41), our department organized China Academy of Building Research Co.
, Ltd.
and other units to revise and form the national standard “Concrete Quality Control Standards (Revised Draft for Comments)” (see attachment).
We are now soliciting opinions from the public.
Relevant units and the public can provide feedback through the following channels and methods:.
Interpretation of century old architecture: The logic behind the failure of concrete price transmission due to the rise in cement prices
During the research process of Century Architecture Network in recent years, a seemingly contradictory phenomenon often appeared: upstream cement companies concentrated on issuing price increase letters, and factory prices continued to rise, but downstream commercial concrete market prices remained stagnant, and even saw raw material prices rise while concrete prices continued to decline.
This deviation in upstream and downstream prices is not simply a result of delayed cost transmission, but rather the fundamental differences in market structure, supply and demand patterns, business models, and funding rules between the cement and concrete industries, combined with weak demand for terminal engineering.

Cement prices rise, but concrete dare not follow, what is the mixing plant owner going through
In recent days, cement factories in many places in Jiangsu and Shanxi have begun to tentatively raise prices.
