Application of triisopropanolamine in cement concrete
Triisopropanolamine can be used together with some superplasticizers used in ready-mixed concrete, such as polyether polycarboxylate water Triisopropanolamine was mainly used in petrochemical and daily chemical industries. It is also a new type of cement grinding aid raw material, which has the characteristics of improving the 28 d compressive strength of cement. After the addition of triisopropanolamine, the workability of the concrete is improved. Advantages: The addition of triisopropanolamine can increase the compressive strength of cement concrete by 15% to 30%. reducer, and can reduce the amount of cement by 10% to 15%. Take C30 concrete as an example. The cement can be reduced by 30 to 45 kg / m3, which can reduce the cost of ready-mixed concrete by 5 to 10 yuan/m3 according to the cost of raw materials, and has good economic benefits. The incorporation of triisopropanolamine into concrete reduces the carbon emissions and oxide emissions from cement production while improving resource utilization efficiency. It is a potential technology for promoting the development of green and low carbon in cement concrete, and has a remarkable society. With the continuous development of China's economy, the demand for expressways will inevitably become more vigorous, which will require higher and higher quality of expressway construction. The prestressed concrete technology has good performance and is very suitable for application in the construction of highway bridges. It will have a great effect on the flexural members of highway bridges and the reinforcement of highway bridges.
