Embodiment Construction
[0026] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0027] A polypropylene fiber sludge ceramsite concrete and its preparation, each cubic meter of concrete contains: 0.91kg of polypropylene fiber, 516kg of sludge ceramsite, 400kg of cement, 180kg of water and 819kg of sand.
[0028] Its preparation method comprises the following steps:
[0029] Step 1, preparing sludge ceramsite, specifically as follows:
[0030] Step 1.1, obtaining raw sludge and dehydrating and drying it, the raw sludge can come from municipal sewer sludge;
[0031] Step 1.2, grinding and homogenizing the dehydrated and dried sludge;
[0032] Step 1.3: Squeeze the homogenized sludge into balls and send it to the ceramsite rotary kiln for firing. The process conditions are firstly preheated at 400°C for 20 minutes, then heated to 1000°C for 20 minutes, and finally cooled naturally in the air;
[0033] In step 1.4, the fired ...

Abstract
The invention discloses a polypropylene fiber-sludge haydite concrete. Each cubic meter of polypropylene fiber-sludge haydite concrete is prepared from the following components in parts by weight: 0.6-1.2kg of polypropylene fiber, 516kg of sludge haydite, 400kg of cement, 180kg of water and 819kg of sand. The invention also provides a preparation method of the polypropylene fiber-sludge haydite concrete. The polypropylene fiber-sludge haydite concrete can serve as a wall body filling material and fills rib cells of a mixed structure of a middle-high layer fabricated type ecological composite wall as an embedded block. With the adoption of the polypropylene fiber-sludge haydite concrete, such disadvantages of the traditional ecological wall body material as low tensile strength, poor ductility and high cracking rate can be overcome, the strength of the polypropylene fiber-sludge haydite concrete is greatly improved, the durability is strengthened, and the treating problem of sludge can also be solved.
Description
technical field [0001] The invention belongs to the technical field of building materials, and relates to a new type of middle and high-rise prefabricated ecological composite wall hybrid structure system, which can also be used in wall materials of ordinary buildings, and particularly relates to a kind of polypropylene fiber sludge ceramsite concrete and its preparation and application . Background technique [0002] As a traditional industry in my country, housing construction has been in the extensive production stage for a long time, with excessive energy and raw material consumption, low industrialization, low labor productivity and technical content, single structural form, and poor building quality and functions, especially residential structures. The anti-seismic safety and comfort need to be improved urgently. The research group organically combined the original ecological composite wall structure with concrete vertical restraint components, learned from each other'...
