Abstract
The invention discloses a kind of environment-friendly engineering C70 self-compacting concrete, every m3Contain lower component: water 120-180 kg, cement 350-400 kg, flyash 60-100 kg, miberal powder 100-140 kg, sand 692-892 kg, rubble 758-948 kg, concrete high efficiency water reducing agent 7.5-9.5 kg in concrete；The present invention is nontoxic, belongs to ep-type material, is mainly used for that reinforcing bar is intensive, difficult position of vibrating；The present invention is nontoxic, belongs to ep-type material, is mainly used for that reinforcing bar is intensive, difficult position of vibrating；Preparation C70 self-compacting concrete proposed by the present invention reduces recruitment cost without manually vibrating；For components such as wall, floor, roof boardings, can not have to vibrate, and expeditiously casting concrete, improve construction quality.
Description
Technical field
The invention belongs to environment-friendly materials technical field, in particular to a kind of environment-friendly engineering C70 self-compacting concrete.
Background technique
Self-compacting concrete (SCC) is a kind of high fluidity and the concrete with proper viscosity, it have not segregability,
Any gap in template can be filled up by reinforcing bar, voluntarily closely knit under the effect of gravity, self-compacting concrete is derived from high-performance
Concrete and be higher than high performance concrete, be the important branch and developing direction of high performance concrete.It is significantly protruded
Feature is that mixture has good working performance, even if under conditions of intensive arrangement of reinforcement and complicated shape or pouring difficulty very
Greatly, under conditions of difficulty of vibrating, can only rely on self weight just can uniformly dense packing effect form without vibrating, and bring for constructing operation
It is greatly convenient.Meanwhile it having concurrently and improving concrete quality, improve construction environment, accelerate construction progress, raise labour productivity, dropping
The techno-economic effects such as low engineering cost, referred to as " the most revolutionary development of concrete technology in nearest decades ".
Self-compacting concrete itself clear advantage, as gel material content is big, sand coarse aggregate ratio is higher, using high efficiency water reducing agent,
The features such as mineral volume is more, therefore design of common concrete proportioning method and principle are no longer applicable in, explore reasonable cooperation
Than design method and according to the specific raw material situation of each department, the self-compaction that development meets the requirement of this area raw material property is mixed
Solidifying soil research and experiment, has very important significance.
Summary of the invention
The present invention provides a kind of environment-friendly engineering C70 self-compacting concretes, to solve the problems of the prior art.
To achieve the goals above, the invention adopts the following technical scheme:
A kind of environment-friendly engineering C70 self-compacting concrete, every m3Contain lower component in concrete:
Water 120-180 kg,
Cement 350-400 kg,
Flyash 60-100 kg,
Miberal powder 100-140 kg,
Sand 692-892 kg,
Rubble 758-948 kg,
Concrete high efficiency water reducing agent 7.5-9.5 kg.
A kind of environment-friendly engineering C70 self-compacting concrete, every m3Contain lower component in concrete:
150 kg of water,
380 kg of cement,
80 kg of flyash,
120 kg of miberal powder,
792 kg of sand,
858 kg of rubble,
8.5 kg of concrete high efficiency water reducing agent.
Further, glue mass ratio when concrete uses is 0.159-0.359, it is preferred that when concrete uses
Glue mass ratio is 0.259.
Further, the sand factor of concrete is 45-50%, it is preferred that the sand factor of concrete is 48%.
Compared with prior art, the invention has the following advantages:
The present invention is nontoxic, belongs to ep-type material, is mainly used for that reinforcing bar is intensive, difficult position of vibrating；The present invention proposes
Preparation C70 self-compacting concrete without manually vibrating, reduction recruitment cost；It, can for components such as wall, floor, roof boardings
