Characteristics and Prospect Analysis of Fiber Reinforced Concrete

Today’s world, concrete is still the most widely used building material in the world. With the continuous development of construction and transportation industry, the requirements for concrete performance are becoming higher and higher, which promotes the research and application of concrete reinforcement materials. Fiber reinforced materials are widely used in concrete materials because of their excellent physical and mechanical properties. Fiber reinforced concrete developed earlier. At present, the research on steel fiber reinforced concrete and polypropylene fiber reinforced concrete has been relatively mature and widely used in engineering practice. However, the research and application of futa fiber, steel wire / steel mesh fiber, polyvinyl alcohol fiber, polyester fiber and Dura fiber on the performance of reinforced concrete are less. This paper introduces the characteristics and applications of the above fiber reinforced concrete, which provides a basis for engineering application....[详细]

What Are The Causes Of Cracks In Mass Concrete?

When the concrete hardens, the moisture decreases gradually, resulting in drying shrinkage. The dry shrinkage is related to the aggregate gradation, cement variety, standard fineness, cement dosage, etc. under the standard state, the limit shrinkage deformation value is generally 3.24*10-4, and 2.5*10-4 for reinforced concrete....[详细]

Causes and Control Measures of Early Concrete Cracks

Crack is the most common defect in concrete engineering, which is divided into macro crack and micro crack. The width of the crack that is not visible to the naked eye is generally referred to as the macroscopic crack width of 0.03mm-0.05mm. Therefore, the visible crack is called macro crack, and the invisible crack with width less than 0.05mm is called micro crack....[详细]

Turning to concrete decoration. On the one hand, it is the need of safety and environmental protection, on the other hand, the exterior decoration of concrete and soil is becoming popular in modern architecture....[详细]

Answers to Basic Technical Questions of UHPC(Reprint)

1.How to finish and cure UHPC? First, for cast-in-situ UHPC without steam curing, the finishing process similar to high-strength silica fume HPC can be adopted. After finishing, the surface shall be covered immediately (e.g. plastic film) or covered while finishing to prevent water loss; Of course, you can also spray high-efficiency curing agent while finishing; Even if the curing agent is sprayed, it shall be covered in time; Premature sprinkling or spray maintenance should not be performed on the surface of UHPC. Sprinkling or spray maintenance can be carried out after pouring 1day.  Second, for the cast-in-situ UHPC to be steam cured, the above methods can also be used for curing within 1day; Steam curing shall be carried out after 1day; Generally, refer to "standard steam curing process", i.e. 90 ° C, 48h; However, pay attention to monitor the temperature and humidity at different locations at any time to ensure uniformity everywhere as much as possible.  Third, for factory prefabricated steam curing or autoclaved UHPC components, the above methods can be referred to or adjusted appropriately....[详细]
