What is the Soundness of Cement?
What is mean by soundness of cement? This is what soundness definition in civil engineering says “The ability of cement to resist the expansion and retain its original volume is called Soundness of Cement.” This indicates that a perfectly sound cement will undergo minimum volume change.
What is the soundness test?
The soundness test measures the change in volume due to expansion. This expansion should not exceed 10 mm for OPC, rapid hardening cement and low heat Portland cements. If the expansion goes more than 10 mm on testing, the cement is said to be unsound.
The soundness test can be conducted by Le-chatelier method and Autoclave Method. Le-chatelier test detects unsoundness due to free lime only.

https://civilinsider.com/compressive-strength-test-on-cement/
The compressive strength of hardened cement is the most important of all the properties. Therefore, it is not surprising that the cement is always tested for its strength at the laboratory before the cement is used in important works.
Why the compressive strength test of Cement is important? Compressive Strength Test on Cement mortar is calculated to find out whether the Cement conforms IS specifications or not and whether it can develop required strength or not when used in Concrete.
Any kind of strength testings are not done directly on Cement itself because of properties like shrinkage and cracking. So Compressive strength test on Cement either done in the form of mortar or concrete. In this article, we will take a look at the compressive strength test of cement mortar using standard sand conforming to IS 650-1991.
Compressive strength of cement is determined by compressive strength test on mortar cubes compacted by means of a standard vibration machine. Standard sand (IS:650) is used for the preparation of cement mortar. The specimen is in the form of cubes 70.6mm*70.6mm*70.6mm.
SIGMA TEST & RESEARCH CENTRE has experience in testing wide range of construction materials,including Cement,Concrete, Aggregates, Admixture, Flyash, Masonary, Tiles, Wood, Steel, Aluminium, Bircks, Query stones,WMM, GSB and many more.

If Cement satisfies all the field tests then it indicates that Cement is not bad for Construction but it also doesn’t show that Cement is really good for Mass work. For using Cement in big and massive works it is dependent on the part of the user to test the cement in the laboratory to confirm the requirements of the Indian Standard specifications respect to its physical and chemical properties.
All the Tests on Cement mentioned here have their own importance. These Cement Tests examines all properties and overall performance of Cement.

What is Consistency of Cement?
Consistency of Cement is amount of water required to initiate the chemical reaction between cement and water to make the uniform cement paste.
Define Standard Consistency of Cement?
Standard Consistency of Cement is defined as Consistency which will permit Vicat plunger with 10mm diameter and 50mm length to penetrate to a depth of 33-35mm from top of the mould.
Standard Consistency of Cement can also be defined as Consistency of cement which will permit Vicat plunger to penetrate to the point 5-7mm from the bottom of the mould.
Also Standard Consistency means the amount of water required to make Cement Paste Plastic.
All aggregate is required to meet a minimum strength valve, as defined by the 10% value test. This and other specifications ensure that only the highest quality materials are being used on construction projects.
How to determine Initial and Final Setting Time of Cement?Civil Insider

https://civilinsider.com/initial-and-final-setting-time-of-cement/
During Construction using concrete, cement paste, mortar certain time is required for mixing, transportation, placing, compacting and finishing. During this time concrete, mortar, cement paste should be in plastic condition and should not harden and it is mandatory that one should use the concrete before it starts to loose its plasticity. So How should someone know how long is concrete workable? and How much travel time is permitted for concrete?
Well its Setting time that tells us how long concrete is going to be workable. Now the question is What is Setting Time of Cement?
This test method is used to determine the time of setting of the cement by VICAT
needle apparatus.
The knowledge of the setting time of the cement is always helpful in deciding the time duration
to mix, transport, place and compact the concrete effectively.
We always prefer a larger initial setting time so that we can mix, transport and place the
concrete easily. According to ASTM specifications, the initial setting time shall not be less
than 45 min but in the field we prefer an initial setting time not less than 90 min.
A smaller value of the final setting time is always preferred in order to avoid large expenditures
on the formwork. According to most of the specifications, the final setting time shall not be
greater than 10hrs and shall not be less than (90 + 1.2 x (initial setting time)) min.
Fineness is tells about the particle distribution of cement. Fineness of is cement expressed in terms of total surface area of unit weight of of cement.

Green Tape for safety glass laminating
Green Tape is to fix pre-laminated glass with EVA FILM, PVB FILM,SGP FILM.
And Green Tape is to perfectly prevent the melt EVA FILM overflowing through laminated glass edges in the oven when heating. Green Tape is high temperature resistance. CNC Green Tape can stand continuously heating more than 180℃ with strong tear resistance.
What is the specifications of Green Tape?
25mm*66M/roll
30mm*66M/roll
35mm*66M/roll
40mm*66M/roll
50mm*66M/roll
......
65mm*66M/roll
980mm*66M/roll
If we use the CNC Green Tape to seal the edges of pre-laminated glass to prevent the exit out of the EVA in the glass laminating oven, will the Green Tape prevent the de-airing vacuuming? do we need to make some holes on the CNC
Green Tape for vacuuming the air out?
It depends. If you don’t make holes on the CNC Green Tape, and you make EVA laminated glass successfully without bubbles, then you don’t need to make holes on the CNC Green Tape, so you can get the cleaner result of the edges of the
final laminated glass. But if you don’t make holes on the Green Tape, but you face bubbles in the corners or edges of the laminated glass, then it’s better you make some holes on the CNC Green Tape to help pre-laminated glass vacuuming.
Does CNC Green Tape leave glues on the glass?
NO! No remains left of CNC Green Tape on glass surface after peeling off. CNC Green Tape can stand continuously heating more than 180℃ with strong tear resistance.

Why evaforce® extreme curved interlayer film better for curved laminated glass
1. WHY EVAFORCE® EXTREME-CURVED INTERLAYER FILM BETTER FOR CURVED LAMINATED GLASS?
BY PETER LIN
Why this extreme curve Eva is better fro curve glass, What the special quality does it have?
EVAFORCE® EXTREME-CURVED INTERLAYER FILM owns advanced modified mechanical properties, like
adhesive strength, to avoid the potential de-lamination of the stress of curved glass.
This EVA is Super clear, if I compare this product with other this is better regarding to Transparency?
EVAFORCE® EXTREME-CURVED INTERLAYER FILM is better at optical transparency, because it's the lowest in
haze.

2. For curve glass what the best thickness of the film? why?
Depends on the how curve it is and the flexion square size.
If the curve is light, then 0.38mm EVAFORCE® EXTREME-CURVED INTERLAYER FILM is OK, if the curve is deep,
then we suggest 0.76mm EVAFORCE® EXTREME-CURVED INTERLAYER FILM.

3. The silicon bag for curve glass is the same used in the flat glass, how the correct procedures to laminate a curve
glass?
For processing curved glass, the time and temperature of heating and vacuuming is the same. But the vacuuming
value should be adjusted to avoid the stress is too high to break the curve glass.

4. When I supposed to use more than one Eva film between 2 glass?
We have 0.38mm and 0.76 mm thickness EVA FILM, you can choose the thickness that meets the situation.
Yes, you can use two layers EVA FILM to laminate together, but if you need to laminate 0.76mm thickness, one layer
of 0.76mm choice is better than 2 layers 0.38 together. Because there will be some air between two layers EVA
FILM.
But if you need thicker EVA FILM, then you can use too layers of 0.76mm to get 1.52mm thickness EVA FILM.
How much thickness EVA FILM is needed? It depends on the situation, for example, if you laminate big size
tempered(rough surface, uneven) glass, then we suggest you use 0.76mm or thicker.

5. I always have to use the green tape? when exactly it is required? for example with curve glass I have to use it?
The use of green tape is not essential, you can choose to use or choose not to use.
The function of green tape is to fix the pre-laminated glass, and sometimes it's used to reduce overflow of EVA FILM
when the heating temperature is high and time is long.
So, the use of green tape is decided by the laminating worker.
