How To Test The Quality Of Fresh Concrete? – Concrete Test

In the construction industry, fresh concrete is one of the irreplaceable basic materials. And the quality of fresh concrete, as a product of self loading concrete mixer trucks, concrete pumps, concrete batching plants and other equipment, is directly related to the safety and stability of the project. Therefore, strict testing of the quality of freshly mixed concrete is one of the key steps to ensure the quality of the project. AIMIX will show you some ways about the fresh concrete quality test. Let’s learn the relevant testing methods together!

Quality Standard of Fresh Concrete

Of course, before carrying out the test, we need to understand the quality standards of fresh concrete. It usually includes strength, consistency, slump, appearance and admixture. Here are the quality standard of fresh concrete produced by the batching plant, concrete pump, self mixer and so on.

  • Firstly, strength is one of the important indexes for evaluating the quality of concrete, which is usually assessed by parameters such as compressive strength.
  • Secondly, consistency refers to the fluidity of concrete, which directly affects the pouring performance during construction.
  • Slump, on the other hand, is an important indicator for assessing the fluidity and plasticity of concrete.
  • In addition, appearance quality is one of the key factors affecting the competitiveness of concrete products in the market.

Let’s explore its testing methods and related processes in depth.

Testing Methods and Processes: Ensuring the Quality of Every Piece of Concrete

After the production of fresh concrete, comprehensive testing of its quality is an important part of ensuring the quality of the project. The following is a description of common testing methods and processes to ensure that each party of concrete meets the standard requirements.

Sampling: Ensuring the Representativeness of the Samples

Sampling is the first step in concrete quality testing. Random samples are taken from the concrete produced by self-loading concrete mixer trucks, concrete pumps or batching plants to ensure that the samples are representative of the entire production batch. A proper sampling method can effectively reflect the overall quality of the concrete.

Strength Testing: Assessing the Load-Bearing Capacity of Concrete

Strength is one of the key indicators for evaluating the quality of concrete. By means of pressure tester and other equipment, concrete samples are tested for compressive strength. During the testing process, attention should be paid to the filling and compaction of the samples to ensure that the test results are accurate and reliable. Strength test results directly indicate concrete’s bearing capacity, crucial for engineering structure safety.

Slump Test: Assessing the Fluidity and Plasticity of Concrete

Slump is one of the most important indicators for assessing the fluidity and plasticity of concrete. The slump of concrete samples is measured by slump testing equipment. The size of slump directly affects the construction performance of concrete produced by the concrete equipment such as the self loading mixer truck. Too high or too low slump will affect the use of concrete. Therefore, reasonable control of slump is one of the keys to ensure the quality of concrete construction.

Appearance Inspection: Ensure the Beauty and Overall Quality of Concrete Products

Appearance quality is one of the important factors affecting the market competitiveness of concrete products. Through visual inspection or the use of appropriate testing equipment, the flatness, colour, cracks and other conditions of the concrete surface are checked. The appearance inspection of concrete products identifies surface defects promptly, ensuring aesthetic quality and boosting market competitiveness.

Process Control and Quality Assurance: Ensuring Stability and Consistency in the Production Process

During the concrete production process, strict control of the parameters is the key to ensuring product quality. Concrete stability is maintained through monitoring and adjusting parameters like mixing time, speed, water-cement ratio in real-time. To ensure stable quality, we must stabilize the production process for each batch of concrete. Therefore, the process control is essential to ensure the quality of high-quality concrete with your concrete pump or the batching plant
