Abstract
The invention discloses a light-weight anticorrosion durable cement precast slab with good toughness. The precast slab comprises following raw materials: cement, rebar and dinas, wherein the dinas is calcium carbonate stone powder; the precast slab also comprises a cement water reduction enhancer, polypropylene fiber, lignocellulose, carboxyl propyl methylcellulose, a cement increment wear-resisting agent, and perlite powder; the parts by weight of the components are as follows: 0.1-0.2 part of cement water reduction enhancer, 0.4-0.7 part of polypropylene fiber, 1.2-1.6 parts of lignocellulose, 1-2 parts of perlite powder, 0.2-0.4 part of carboxyl propyl methylcellulose, 1-2 parts of cement increment wear-resisting agent, 28-32 parts of cement, 60 parts of calcium carbonate stone powder, and 20 parts of water. The cement precast slab prepared by the raw materials has light weight, good toughness, good corrosion resistance and long service life, is not easy to break, and is bright and attractive.
Description
Technical field
The present invention relates to cement pre-fabricated panel, particularly a kind of lightweight, good toughness, anticorrosion durable cement pre-fabricated panel.
Background technology
Being of wide application of cement pre-fabricated panel, as the thermal baffle for road and bridge, top, house, methane-generating pit, septic tank, water conservancy channel, sewer line etc., but existing cement pre-fabricated panel is often heavier, and easy fracture is immalleable.
Summary of the invention
The object of the invention is to provide a kind of lightweight, good toughness, anticorrosion durable cement pre-fabricated panel.
The technical scheme that realizes the object of the invention is:
A kind of lightweight, good toughness, anticorrosion durable cement pre-fabricated panel, its formula material comprises cement, reinforcing bar and sandstone, unlike the prior art: described sandstone is calcium carbonate stone powder, in formula, also contain cement water-reducing strengthening agent, polypropylene fibre, lignocellulose, carboxylic propyl methocel, cement increment anti-wear agent, perlite powder, its formula materials and materials weight part ratio are except reinforcing bar is by the prior art increase and decrease of purposes, and each component materials weight part proportioning is:
Cement water-reducing strengthening agent 0.1-0.2
Polypropylene fibre 0.4-0.7
Lignocellulose 1.2-1.6
Perlite powder 1-2
Carboxylic propyl methocel 0.2-0.4
