Thermogravimetric analyzer (TGA)

The thermogravimetric analyzer (TGA-550, TA instruments) can determine sample composition by measuring the weight of each component as it volatilizes or decomposes under controlled conditions of temperature of up to 1000ᴼC.

 

 

Isothermal calorimeter

The isothermal calorimeter (TAM Air-8-channel, TA instruments) can monitor the heat flow during cement hydration in a temperature range of 5 to 90ᴼC. Additional admix ampoules can be used to evaluate the effects of chemical admixtures or activators on cement hydration.

 

 

 

 

Dynamic vapor sorption (DVS) analyzer

DVS (Q5000 SA, TA instruments) has the capability to perform sorption analysis of materials under controlled conditions of temperature and humidity. It can operate at a temperature range of 5 to 85ᴼC and 0 to 98% RH. Vapor sorption isotherms are useful to evaluate nano to micro-structural porosity and specific surface area of composite materials, including hydrated cement paste and ceramics.

Chloride permeability meter

The rapid chloride permeability meter is used to measure the resistance of concrete against the penetration of chloride according to the standard methods such as ASTM C1202, AASHTO T277, and ASTM C1760. The measurement data can be used to estimate the chloride diffusion coefficient of concrete for the service life prediction and design of concrete structures as well as the durability-based quality control of cement-based materials.

 

Carbonation chamber

The carbonation chamber can be used to expose samples to an environment containing up to 30% CO2 concentration at controlled relative humidity and temperature.

Automated titrator

The automated titrator can analyze up to seven samples continuously. This is mostly used to determine the chloride contents and diffusion coefficient in cement-based materials.

Planetary Ball mill

The Planetary Ball Mill is designed for mixing, fine grinding, and preparing small volume high-tech material production, which features with small volume, high efficiency, low noise, and lock clamps. It has four ball grinding tanks installed on one turning plate. When the plate rotates, the tank axis makes the planetary rotation in opposite directions and the balls in the tanks grind and mix samples in high-speed movement. The product can smash and blend various products of different materials and granularity with dry or wet methods.

 

 

 

Low Speed Diamond Saw

This low-speed diamond saw can be used for cutting, dicing, and slicing brittle composites including ceramics and cement-based materials. It comes with a digital micrometer, digital speed display as well as complete accessories. It accepts 6-inch and 4-inch cutting blades.
