Device standard: AASHTO T153. EN 196-6. ASTM C204
Blin (softness) cement device is used to determine the specific surface of the particles and as a result the softness of the cement. The size of cement particles plays a significant role in the hydration rate of cement when in contact with water. The specific surface area of cement is a function of the size of cement particles. The finer the cement particles, the larger the specific surface of the cement. .
It has a pack of 100 pieces of blain filter.
Includes a perforated brass filter.
Automatic cement blain device, a device to determine the softness of Portland cement based on
The special surface is used in the way of air permeability in the material.
Considering that there is user error in manual devices, the automatic balin device
is produced to prevent user error. The way this device works is the same as other devices
but with the difference that when the start process of the suction device is started, it is sucked by an automatic suction device that
is very sensitive and precise with ten millimeters accuracy.
The softening process of cement in the form of a specific surface is measured by observing the amount of time it takes for a constant amount of air to pass through the compacted cement floor with known size and porosity level. nBlin test (the level of cement softness) is a quantitative test, and for this reason, the use of reference and tested cement is necessary to compare the results obtained with the results of the reference cement test. r\nIf the cement that is used has smaller grains, its contact surface will increase
and as a result, its specific surface will also increase. The size of the cement grains has a great impact on getting it in the right place, especially when making all kinds of concrete; Sometimes we need concrete that is fast.
In this case, instead of using materials and additives that often have adverse and bad effects on concrete, we use cement that has different levels of softness. In fact, the amount of these granulations are divided into types 1-5 according to the softness and fineness of the cement grains.
Testing stages of the Blain machine:
First stage
In this stage, first, a mesh screen is placed inside the cylinder of the machine. We put it, then we put the special filter paper inside the tank (Cell Blain) and put it on the mesh screen and weigh a specific amount of cement and pour it into the tank of the machine. Now, we smooth the surface of the cement with slow strokes that we enter into the tank.
Second step
In this step, we put another smoothing paper exactly on the cement, and the plunger (piston) We fill the tank until its cap reaches the end of the cylinder. We compress the cement floor completely and now pull out the piston. Third step In this step, place the permeable tank on the T pipe. Let's make a shape and we have to make sure of the sealing
of the pipe.
To make sure of the sealing
