Problems solved by technology

The cured mud is used as the raw material for brick making, most of which will become barren materials during the high temperature sintering process, which will have an adverse effect on the sintering strength. After sintering, the strength of the brick product is very low or has no strength, so it cannot meet the requirements Requirements for firing ordinary standard bricks

Embodiment 1

[0012] Embodiment 1: the proportioning (percentage by weight) of curing agent is high alumina cement 18%, portland cement 18%, shale 64%, mud density is 1.2g / cm 3 Add the above-mentioned proportioning curing agent of 40% of the weight of the mud into the mud, and use it as a brick-making raw material to make bricks according to the standard sintered brick process after curing. After testing, the performance indicators of the ordinary sintered bricks made are as follows:

[0013] Sintered ordinary brick Y240 * 115 * 53, design strength level: MU10

[0014] test result:

[0015] Average compressive strength: 28.1MPa

[0016] Single minimum strength: 22.2MPa

[0017] Coefficient of variation: 0.14

[0018] Inspection intensity level: MU25

Embodiment 2

[0019] Embodiment 2: the proportioning (percentage by weight) of curing agent is high alumina cement 15%, portland cement 19%, shale 66%, mud density is 1.8g / cm 3 Add the above-mentioned proportioning curing agent of 20% of the weight of the mud into the mud, and use it as a raw material for making bricks to make bricks according to the standard sintered brick process after curing.

Abstract

The present invention relates to production of standard sintered brick, and is especially process of producing sintered brick with drilling mud. Drilling mud is first cured via adding curing agent in 10-50 wt% and then used in producing sintered brick through one standard sintered brick producing process. The curing agent consists of high alumina cement 15-20 wt%, Portland cement 15-20 wt% and silt soil 60-70 wt%. The present invention changes waste into useful material and is environment friendly.

Description

(1) Technical field [0001] The invention relates to a production method of standard sintered bricks, especially a production method of making sintered bricks with drilling mud. (2) Background technology [0002] Ordinary standard sintered bricks mainly use clay minerals such as shale as raw materials. Many important physical properties of sintered bricks, such as plasticity and strength, depend on the composition of clay minerals. When the stone, hydromica (illite) or similar components are used, this raw material is suitable for the preparation of sintered bricks. However, after the existing curing agent solidifies the drilling mud, its components are very different from clay minerals. The cured mud is used as the raw material for brick making, most of which will become barren materials during the high temperature sintering process, which will have an adverse effect on the sintering strength. After sintering, the strength of the brick product is very low or has no strength...
