Material for the manufacture of wood grain look self-compacting concrete
Technical field
The present invention relates to a kind of material of construction, relate in particular to a kind of material for the manufacture of wood grain look self-compacting concrete.
Background technology
Concrete is to be disposed by suitable proportion by gelling material, aggregate and water, the artificial stone material that sclerosis forms through certain hour again.Concrete hardness is high, sturdy and durable, raw material sources are extensive, making method is simple, with low cost, plasticity-strong, be applicable to various physical environments, be culture's material of in the world usage quantity maximum, be widely used in the structures such as house, bridge, highway, runway, retaining wall, bank protection, culvert, dam, water tank, water tower, oil groove, channel, ditch, harbour, seawall, military fortification, nuclear plant.
CN201110316681.9 provides a kind of high-strength high-performance concrete, it is characterized in that: comprise following component, cement 270-430kg, flyash 30-100kg, breeze 30-100kg, sand 650-750kg, stone 1050-1200kg, water 110-160kg, admixture is prepared from.The present invention utilizes popular material, by various mixing proportion design methods and a large amount of concrete test, having drawn strength grade is the high-strength high-performance concrete of C60, C70, C80, C90, C100, intensity is high, good endurance, can be used for the various engineerings under high level, large span and the mal-condition environment.
CN200810163848.0 provides a kind of concrete, relate in particular to a kind of debris concrete, comprise cement, water, stone, flyash, breeze, river sand and admixture, it is characterized in that: also comprise chip, this chip is the tailing that screens in the process of mechanical workout ore, the particle diameter of described chip is between 0.1-5MM, and the particle diameter of described stone is between 5-25MM; Wherein cement is 200-292KG, and water is 185-190KG, and stone is 1043-1088KG, flyash is 56-75KG, and breeze is 44-85KG, and river sand is 152-257KG, admixture is 5.1-7.7KG, and chip is 534-599KG, more than each component all by weight percentage.Production cost of the present invention is low, and concrete density and anti-permeability performance are good.
At present, still there is not a kind of available self-compacting concrete.
Summary of the invention
The purpose of this invention is to provide a kind of material for the manufacture of wood grain look self-compacting concrete, obtained the self-compacting color concrete of constructability, enhancing concrete appearance color.
A kind of material for the manufacture of wood grain look self-compacting concrete comprises basic components and colour developing prescription in every cube of concrete.
Basic components is: 162.4~166.3 kilograms in 246~252 kilograms of cement, 98.4~100.8 kilograms of slag micropowders, 752.8~771.1 kilograms of yellow ground, 1031.2~1056.4 kilograms of rubbles and water.
Colour developing prescription is: 4.13~4.23 kilograms of 49.2~50.4 kilograms of titanium dioxides, 0.98~1.01 kilogram of iron oxide yellow, 0.49~0.50 kilogram of iron oxide red and special-purpose polycarboxylate water-reducers.
The micro mist of slag micropowder for being made by the resistates after ore process ore dressing or the smelting, it is the raw material that this area is commonly used.The slag micropowder that the preferred S95 level of the present invention is above.
Rubble is not particularly limited, the raw material of commonly using for this area.Should adopt the collocation of continuous grading or 2 and above one-stone grading to form, nominal maximum aggregate size is no more than 20mm.
Material for the manufacture of wood grain look self-compacting concrete provided by the invention does not need to vibrate, and just can be used for building the structure of forming shape complexity, thin-walled and intensive arrangement of reinforcement, improves concrete surface quality.The self-compacting concrete of making realizes that strength grade of concrete is C35, and apparent presenting colors wood grain look open bubble or honeycomb and scale can not occur, does not need to carry out skin patching, can true to naturely present texture or the moulding of template surface.
After adding the colour developing prescription, obtain color concrete.So can make the face of building for good and all present various color and lusters, pattern, texture, realistically the material of simulating nature and texture, indiscriminately ad. as one wishes all kinds of patterns of cropping, and new, make people realize like a cork buildings and humanistic environment, physical environment is got along amiably and peacefully, the ideal that combines together.According to owner's needs, Designers's creating conception is developed uniqueness and applicable color artistic concrete product and embossment replaced existing decoration of exterior wall.
Embodiment
Below describe technical scheme of the present invention in detail.
