Embodiment Construction
[0019] The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0020] The purpose of this embodiment is to provide a method for surface treatment of ceramsite raw materials to improve the cylinder compressive strength of the spherical silicate ceramsite product in view of the lack of cylinder compressive strength.
[0021] This implementation adopts the following technical solutions:
[0022] Screen seven ceramsite samples with a nominal particle size of 10-20 mm, of which sample 1 is not treated (control group); samples 2 and 3 are treated by spraying, and silane (WS 808) and ethyl silicate (dynasylan A) solution was sprayed on the surface of the ceramsite respectively, and the treated ceramsite was dried in the natural state of the room for 48 hours, and the drying effect was...

The invention provides a ceramsite surface enhancing method for concrete and surface enhanced ceramsite, the ceramsite surface enhancing method comprises the following steps: step 1, preparing a ceramsite surface treatment solution, the ceramsite surface treatment solution being silane or ethyl silicate; step 2, carrying out infiltration treatment on the surface of the ceramsite by adopting a ceramsite surface treatment solution; step 3, carrying out drying treatment on the ceramsite; and 4, testing the cylinder compressive strength, the bulk density and the water absorption rate of the ceramsite. On the premise that the bulk density is not greatly changed, the cylinder compressive strength of the ceramsite can be improved by 50%, meanwhile, the water absorption rate of the ceramsite is reduced and is about 30% of that before treatment, and favorable technical support is provided for later preparation of high-strength lightweight aggregate concrete and development of lightweight and high-strength performance of ceramsite concrete.
Description
technical field [0001] The invention relates to the technical field of concrete preparation, in particular to a method for strengthening the surface of ceramsite used in concrete and the ceramsite for surface reinforcement. Background technique [0002] Ceramsite is a kind of ceramic particles made of industrial waste as the main raw material, which is cheap, environmentally friendly and pollution-free. Due to different production processes, the shapes of ceramsite are different, and the appearance characteristics are generally round or oval spheres, and some gravel-type ceramsite is in the shape of irregular gravel. Due to its light weight and porous characteristics, it is often used to prepare lightweight aggregate concrete in construction. In the preparation of concrete, ceramsite can replace part or all of the stones and configure it into lightweight aggregate concrete. Under the requirement of design strength, it can generally reduce its own weight by 30%-40%, achievin...
