What is unsoundness of cement?
when we test the cement with the help of Le-Chatlier apparatus and then we found if the expansion is more than 10 mm then the cement is said to be unsoundness
What material will be used for sine bar apparatus?
stbilized steel
What is soundness of cement?
Soundness of cement is the property of hardened cement paste undergoing large change in volume after setting without delayed destructive expansion. This destructive expansion is caused by excessive amounts of free lime or magnesia. This change in volume may cause crack and disintegration of concrete.Soundness of cement can be checked by using Le-Chatliers apparatus.

What is the English and foreign plural form of the apparatus?
The Latin plural of the noun apparatus is actually apparatus (the vowel lengthens, but that's not reflected in the spelling). The English plural is apparatuses. You don't actually hear the English plural apparatuses that often, because apparatus is treated as a semi-uncountable noun: one apparatus, two pieces of apparatus. "Apparati" is incorrect in either language.
What is a pressure cooker-like apparatus used to sterilize instruments called?
Autoclave.
Number of samples for autoclave expansion test for portland cement?
one
Linear expansion apparatus?
Linear expansion apparatus is the apparatus used to measure the objects to these following properties: -> coefficient linear expansion -> coefficient thermal expansion -> specific gravity -> specific heat -> thermal conductivity -> thermal resistivity -> breaking strength and many others..
What is the function of autoclave in the laboratory?
An autoclave in the laboratory is used to sterilize equipment and supplies by using high pressure and high temperature steam. This process ensures that any microbial contaminants are destroyed, making the equipment safe for use in experiments and procedures.
What water do you use in an autoclave?
Demineralised water should best be used in an autoclave.
What apparatus is commonly used in lab to show expansion of solid on heating?
A common apparatus used in labs to show the expansion of solids on heating is a simple demonstration setup consisting of a metal ball and ring. The ball passes easily through the ring at room temperature, but when heated, it expands and no longer fits through the ring, illustrating the concept of thermal expansion.
What organism is used for testing the efficiency of autoclave?
Geobacillus stearothermophilus spores are commonly used for testing the efficiency of an autoclave. These spores are resistant to high temperatures and can be used as a biological indicator to ensure that the autoclave is properly sterilizing equipment.
What is air expansion apparatus?
is air expantion a chemical or physical change?
What is difference between autoclave and oven?
In simple words, autoclave is a pressurized oven.
What is the meaning of autoclave pound?
It seems there may be a misunderstanding. An autoclave is a machine used for sterilizing equipment or objects using high pressure and steam. There is no standard meaning for "autoclave pound" in this context.
What type of water must be used in a steam autoclave?
Distilled water should be used in a steam autoclave to prevent mineral deposits and prolong the life of the equipment. Using tap water or other types of water can damage the autoclave and compromise the sterilization process.
What are the functions of air expansion apparatus?
a device that demonstrate how heat affects the volume of a gas.
