Embodiment 2

[0080] The ratio of raw materials in this embodiment is 35% of oilfield sludge, 20% of river sand, 20% of cement, 24% of fly ash, and 1% of curing agent.

[0081] Wherein, the curing agent is mixed with the raw materials in the following weight ratio:

[0082] Sulfoaluminate: 15% Calcium Stearate: 2%

[0083] Calcium Chloride: 10% Calcium Acetate: 15%

[0084] Fluorite: 10% Gelatin: 9%

[0085] Gypsum: 10% Lime: 25%

[0086] Acrylic 4%

[0087] After oilfield sludge, river sand, cement, fly ash, and curing agent are mixed evenly, the slurry material is loaded into a mold, pressed on a press with a pressure of 650KN, demolded, and dried to make a finished product.

[0088] The performance test results are: the average 28-day compressive strength is 16.66Mpa, and the 28-day flexural strength is 5.65Mpa. Its mechanical properties can still meet the relevant national standards. Other properties are substantially the same as in Example 1.

Abstract

The present invention relates to no-baking brick, and is especially no-baking brick made of oil field sludge and its production process. The no-baking brick of the present invention is produced with the following material and through mixing and extrusion in extruder: oil field sludge 30-60 wt%, river sand 15-40 wt%, cement 15-30 wt%, flyash 0-35 wt% and curing agent 1-8 wt%. The no-baking brick of the present invention has high strength, no pollution and simple production process, and the present invention solves the problem of pollution and exhaust of oil field sludge.

Description

(1) Technical field [0001] The invention relates to a burn-free brick and a production method thereof, in particular to a burn-free brick made from oilfield sludge and a production method thereof. (2) Background technology [0002] Oil well mud is the blood of oil drilling engineering. With the development of the petroleum industry, the output of oil well mud is increasing, and these numerous oil well muds generally contain a large amount of heavy metals, oils, alkalis and chemicals (including organic matter) substances that are extremely harmful to humans, animals and the environment. If mud is discarded after use, if it is not treated, these substances will seriously pollute the environment, endanger people's life and health, and affect the growth and development of animals and plants. [0003] The treatment and application of oily sludge is a difficult problem in the process of oily sewage treatment. Western Europe and the United States have used biotechnology, physical...
