Description

Paint dreg concrete

Technical field

The present invention relates to a kind of concrete, especially belong to a kind of paint dreg concrete.

Background technology

Along with developing rapidly of paint industry; it is also increasingly outstanding that paint slag is processed problem; for tackling this problem; on the one hand; for protection of the environment, reduce and pollute, national environmental protection department has formulated some very strict requirements to the processing of paint slag; on the other hand, industrial technology personnel are trying to explore the technology of low-cost processes paint slag.At present, if transfer to chemical substance to process a processing according to normal channel, the processing costs of paint slag per ton is greatly about 3000 yuan of left and right, high processing costs makes corporate boss be difficult to bear, therefore, in the face of the situation that quantity is large, expense is high, many enterprises often select illegally privately to process, and environment is caused to a large amount of pollutions.

Summary of the invention

The problem existing for solving prior art; the present invention aims to provide a kind of paint dreg concrete; this paint dreg concrete be take silicate series cement as gelling material; it is fine aggregate that paint slag adds common river sand; rubble is coarse aggregate; add water again and admixture is formulated, at the bottom of thering is utilization of waste material production cost especially, thereby for paint slag is processed, environment protection is made contributions.

For solving the problems of the technologies described above, the present invention has adopted following technical proposals: this paint dreg concrete, comprise cement, water, river sand, rubble and admixture, it is characterized in that: also comprise paint slag, this paint slag is the waste material producing after the polishing of furniture lacquer painting, the particle diameter of described rubble is between 5-25cm, and described admixture is water reducer; Calculate by weight, each component proportion is (kg/m3): cement 300-360kg, water 210-230kg, rubble 1090-1170kg, river sand 200-300kg, admixture 1.20-1.44kg.

As preferably, described admixture is wooden calcium water reducer.

As preferably, described paint cinder ladle is drawn together paint ground-slag end.

As preferably, the fineness modulus of described river sand is 3.0-2.3, and median size is 0.5-0.35mm.

Beneficial effect: take silicate series cement as gelling material, to add common river sand be fine aggregate to paint slag, and rubble is coarse aggregate, adds water and chemical admixture, the according to a certain ratio concrete of preparation so far there are no report.The present invention is from the main ancestor of utilization of waste material, and with paint slag and powder Substitute For Partial river sand thereof, thereby the object that realizes utilization of waste material and save natural resources produces economic benefit to society, eliminates environmental pollution.From experimental data, in intensity, normal concrete is that to take cement, rubble, river sand be adulterant, and paint dreg concrete is that to take cement, rubble, paint slag be adulterant, the strength ratio river sand of paint slag is low, so by same proportioning, paint dreg concrete is lower than normal concrete intensity, be applicable to doing the buildings such as blinding layer below C20 and roadbed ash soil layer; From weight, analyze, due to the light capacity of volume ratio river sand of paint slag, so paint dreg concrete is wanted gently with normal concrete, the most applicablely make building block, do the buildings such as infilled wall in skeleton construction.With paint slag Substitute For Partial river sand, make paint dreg concrete, not only can reduce production costs, even more important is to have realized utilization of waste material object, thereby for minimizing is polluted, protection of the environment contributes.

Admixture of the present invention is wooden calcium water reducer, and its water-reducing rate is 8-10%, certainly also can adopt other ordinary water-reducing agent or high efficiency water reducing agent as required.This paint dreg concrete go out the machine slump between 1-4cm, the different ultimate compression strength in the length of time of normal temperature maintenance (MPa) are: between 16 hours strength of mould stripping 0.5-0.9, within 3 days, strength of mould stripping is between 5.1-5.5, within 7 days, strength of mould stripping is between 9.7-10.8, between 28 days strength of mould stripping 14.4-18.8.The index of these data and C15, C20 level normal concrete is close, therefore, can be used for different fields, for example: 1, for making light weight concrete, be made into the building block for building used for filler wall, its proportioning is that to paint slag, cement, water and admixture be main raw material(s), and according to design requirements preparation, reaching that design strength requires is the light weight concrete of standard; 2, the concrete of using for construction work basis packing course or highway subgrade ash soil layer, its proportioning is that to paint slag, cement, river sand, rubble, water and admixture be main raw material(s), according to design requirements preparation, reach design strength and require as the low-grade concrete of standard; 3, Schwellenwert, maximum, the optimum value of paint dreg concrete: (a) proportioning of the Schwellenwert of paint dreg concrete is pure paint slag, cement, water and admixture, feature is that the proportioning of maximum lightweight, intensity is low (b) paint dreg concrete is paint slag, cement, river sand, rubble, water and admixture, feature is that volume is heavy, the proportioning of the optimum value of intensity high (c) paint dreg concrete is paint slag, cement, river sand, water and admixture, feature is that weight is moderate, moderate strength, use range are wide, is conducive to multiple construction purposes.

The main component of paint slag is resin and calcium carbonate, and this bi-material can produce good cohesive force with silicate cement, and by experiment, the performance of paint dreg concrete is basic consistent with normal concrete.

Embodiment

Below by embodiment, be described further.

Embodiment:

Raw material of the present invention comprises cement, water, paint slag, river sand, rubble and admixture, and wherein admixture is wooden calcium water reducer, and water-reducing rate is 10%.Prepare the amount of required each component of paint dreg concrete of the present invention in Table 1.

Biao1:(unit: kg)

Each embodiment in table 1 is the formula that forms paint dreg concrete, and wherein the unit of each component institute consumption is kg, in weight part.Cement type adopts respectively 32.5 grades and 42.5 grades of Portland cements.Ballast grain sizes is between 5-25mm.Described paint cinder ladle is drawn together its particle diameter of paint powder does not have particular requirement.

Embodiment 1 take below as example, to preparing the making method of the paint dreg concrete of the present invention of 1 cubic metre, describe: first take successively paint caye 510kg, cement 230kg, river sand 250kg, rubble 1160kg, wooden calcium water reducer 1.24kg, put into common forced action mixer, opening whip switch starts to stir, after stirring, inject the 230kg of institute water, stir 5 minutes above.

Press the formulated paint dreg concrete of different ingredients in table 1, there is different intensity, as embodiment 1, embodiment and embodiment 3 are respectively C15; Embodiment 4 is C20.

Table 2:

Embodiment	The slump (cm	28d strength of mould stripping (MPa)
			1	3-4	15.0—16.3
2	1	16.3—18.8
			3	2-4	14.4—16.4
4	3-4	16.6—18.2

As known from Table 2: paint dreg concrete of the present invention has good performance, density and intensity all meet the corresponding requirement of normal concrete, therefore, by the technical scheme of paint slag Substitute For Partial river sand preparation paint dreg concrete, are feasible.His maximum feature is: will be to chemical objectionable impurities---paint slag, from formulated, become solid, harmful chemical substance is carried out to permanent closure processing, do not produce secondary pollution, also as material of construction, be fully used simultaneously, for Harmful chemicals, process and found a new treating method.

Above-described embodiment is only for explaining invention thinking of the present invention, and any equivalence or simple change that is subject to its inspiration and makes, all should include protection scope of the present invention in.
