how to make a clay brick in the lab
(OP)
I am a researcher in civil engineering materials specializing in asphalt mixes. I am doing research in recycling idusterial solid waste as a construction material.I have used waste materials in concrete and asphalt in the past. I am trying this time to utilize two wastes in clay bricks which is a new area to me. The first waste is a spent Zeolite catalyst pwder (Ecat) generated from oil refinary operations. The seconed waste is an air dried solid sludge cake obtained from the textile effluent treatment plant, which will be pulverized before mixing with red clay.
I am thinking to prepare 70X70X70 mm cubes and fire them in a muffel furnace at different emperatures. I am not sure how to properly mix the materials to get red of all the air inside and avoid cracking during the firing process. Any ideas, standards, and specifications for the mixing, firing and the testing to evaluate the new products and compare them to the standard normal clay bricks ?

If you consult the industry, you'll likely only get info on large batches, which will sometimes not work well with small batches and your available equipment. The local crafts instructors are used to working with small batches and minimal equipment.

Consequently, any lab attempts will be impossible to correlate to a new production process unless the material and their properties can be correlated and combined and matched to a typical process.
There is very little correlation between pottery and fired clay brick, especially of the shape and configuration (cored vs. solid) is included. The "red" color is often an indication of the amount of iron in the brick, but other minerals can be combined to give the "red clay brick" appearance.

The clay I am using will be supplied to me in a powder form by a local brick making factory.
Any body is aware of the relavent standars or specifications for quality control in the lab.

There are some progressive manufacturers that are faced with limited availability of natural resources.

(Concretemasonr): I contacted a manufacture of bricks,he will supply me with ground red clay free of charge. However, he cant mix the stuff for me in the plant or fire it, because of small quatities of waste materials I have, and because he cant disturb his production process.
Ibrahim demir : I think steem cooking you refered to is good in concret, this is an autoclaving process that wel speed up the hydration rate of concrete. In clay we have to fire ( burn ) the brick, it is a completely different mechanism.

Make sure you fire the clay samples at the proper temperature for chemical properties of the clay sample. The firing temperatures have an effect of the properties of the finished product. The dimensions of the samples may also have an effect on the properties and dimensional stability.
Trying to match lab samples with the real world is a very difficult challenge.
