Product introduction

The concrete carbonation test box is a special equipment for concrete carbonation test, and the products meet the requirements Requirements for carbonation test equipment in GB / t50082-2009 "standard for test methods of long term performance and durability of ordinary concrete". This machine adopts the original imported carbon dioxide analyzer: the analyzer adopts the infrared detection principle, combined with the domestic advanced intelligent touch screen instrument, and has the characteristics of high precision, long service life and simple operation. The temperature and humidity sensor is composed of domestic advanced integrated induction module and intelligent instrument. This product has the characteristics of high control precision, simple operation, intuitive digital display and timing recording of temperature, humidity and concentration in the box.

Executive Standards

GB / t50082-2009 standard for test methods of long term performance and durability of ordinary concrete

JG / t247-2009 concrete carbonation test box

DL / t5150-2001sl352-2006 test code for hydraulic concrete

Jtj270-98 "test specification for concrete in water transportation engineering"

working principle

The concrete carbonation test box is a sealed box. The test pieces are placed on the partition board inside the box, and then controlled by digital control instrument according to the set temperature, relative humidity and carbon dioxide concentration to ensure constant temperature, constant humidity and constant carbon dioxide concentration in the box

Main structure    

     The carbonization test chamber is mainly composed of box, temperature and humidity and carbon dioxide concentration control system. The outer plate of the box is made of cold-rolled steel plate, the inner tank is made of high-quality stainless steel plate, and the clapboard is made of stainless steel profile, which has good moisture retention, sealing and corrosion resistance.
