Abstract
The invention discloses a device for determining internal relative humidity and temperature of cement concrete, relates to a device for determining relative humidity and temperature, and particularly relates to the device for determining internal relative humidity and temperature of the cement concrete, in order to solve the problem that a device capable of determining the internal relative humidity and temperature of the cement concrete is not available at present. The device comprises a round pipe, a temperature and humidity sensor element, a data collector and a computer, wherein the temperature and humidity sensor element is connected with the data collector through an electric wire; the temperature and humidity sensor element is arranged inside the round pipe; one end of the round pipe is sealed by a waterproof material; the other end of the round pipe is sealed by a waterproof breathable film encapsulation material; and the data collector is connected with the computer. The device disclosed by the invention is used for determining the internal relative humidity and temperature of the cement concrete.
Description
Technical field
The present invention relates to a kind of mensuration relative humidity and temperature device, be specifically related to a kind of device of measuring cement concrete internal relative humidity and temperature.
Background technology
Cement concrete material is one of global consumption maximum, the most widely used manufactured construction materials.Because concrete has applied widely, low price, easily build moulding, the advantage such as more durable, bringing into play the irreplaceable effect of other material in numerous building engineering fields, but cement concrete also have bending resistance draw low by force, under ultimate tensile strength, the early stage dry dehydration that is easy to shrink shortcoming, the especially cement concretes such as cracking shrink to its usability and serviceable life important.
The early-age shrinkage of cement concrete cracking is a very complicated engineering problem, causes with non-load and causes two types if the cracking of cement concrete is divided into load, and the crack of cement concrete nearly 8% is caused by non-load factor according to statistics.In decades, although the development of cement concrete subject has obtained many progress, early stage cracking phenomena is still commonplace after cement concrete is built in the past.Investigation at home and abroad finds that in present many large-scale cement concrete workses, ubiquity serious crack problem, and the time that the crack occurs is all generally within several days initial stage that cement concrete strength forms.
The dry dehydration Shrinkage behavior of cement concrete is the principal element that affects the early stage cracking of cement concrete, and the cement concrete drying shrinkage is mainly relevant with cement concrete internal relative humidity and temperature variation that outside health-preserving condition causes.Outside health-preserving condition is easy to detect, but obtaining of cement concrete internal relative humidity and temperature is more difficult.At present, also do not have a kind of device to measure relative humidity and the temperature of cement concrete inside.
Summary of the invention
The present invention is for solving the problem that does not also have a kind of device to measure relative humidity and the temperature of cement concrete inside at present, and then proposes a kind of device of measuring cement concrete internal relative humidity and temperature.
The present invention addresses the above problem the technical scheme of taking to be: the present invention includes pipe, Temperature Humidity Sensor element, data acquisition unit and computer, the Temperature Humidity Sensor element is connected with data acquisition unit by electric wire, the Temperature Humidity Sensor element is arranged in pipe, one end of pipe seals with waterproof material, the other end of pipe seals with the waterproof breathable membrane encapsulating material, and data acquisition unit is connected with computer.
The invention has the beneficial effects as follows: the present invention can realize the measurement of cement concrete internal relative humidity and temperature, can build internal relative humidity and the temperature variation that reaches in forming process in early stage health process by the METHOD FOR CONTINUOUS DETERMINATION cement concrete; The present invention can be used for comparative analysis and the research of the early stage shrinkage performance of cement concrete.
