Abstract
The utility model discloses a model test block for temperature and crack tests of basic mass concrete, which comprises a cubic template, wherein an expanded polystyrene layer is arranged on the inner cavity wall of the template, poured concrete is arranged inside the expanded polystyrene layer, a layer of plastic film is arranged between the concrete and the expanded polystyrene layer, and a temperature sensor and a concrete strain meter are embedded in the concrete. The developed model test block is used for conducting temperature and crack tests on the basic mass concrete, concrete performance can be tested before pouring of a concrete foundation, and the concrete can be adjusted according to test results simultaneously.
Description
Technical field
The utility model relates to base mass concrete temperature and crack testing research.
Background technology
The performance requirement of base mass concrete is very tight, therefore need test accordingly with correspondence and adjust concrete component and proportioning.This just need test the performance of base mass concrete before the casting concrete basis.
The utility model content
The utility model technical matters to be solved just provides a kind of base mass concrete temperature and crack test model test block, through this model test block base mass concrete is carried out temperature and crack test.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: base mass concrete temperature and crack test model test block; It is characterized in that: comprise the cube template, said template internal chamber wall is provided with one deck expanded polystyrene (EPS) layer, the concrete for building in the expanded polystyrene (EPS) layer; Be provided with layer of plastic film between said concrete and the expanded polystyrene (EPS) layer, be embedded with temperature sensor and concrete strain gauge in the said concrete.
As preferably, said template is the cube of length of side 100cm.
As preferably, the thickness of said expanded polystyrene (EPS) layer is 10cm.
As preferably, the test point at concrete edge is positioned at the scope from concrete surface 2cm in said temperature sensor and the concrete strain gauge.
The utility model carries out temperature and crack test through this model test block of developing to base mass concrete, can be before the casting concrete basis, and the test concrete performance simultaneously according to test result, is adjusted concrete.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the model test block structural representation of the utility model;
Fig. 2 is temperature test point distribution schematic diagram in concrete;
Fig. 3 is stress test point distribution schematic diagram in concrete.
Embodiment
Extremely shown in Figure 3 like Fig. 1; Embodiment for the utility model base mass concrete temperature and crack test model test block; Comprise cube template 4, said template internal chamber wall is provided with one deck expanded polystyrene (EPS) layer 3, the concrete 1 for building in the expanded polystyrene (EPS) layer; Be provided with layer of plastic film 2 between said concrete and the expanded polystyrene (EPS) layer, be embedded with temperature sensor and concrete strain gauge in the said concrete.Said template is the cube of length of side 100cm.The thickness of said expanded polystyrene (EPS) layer is 10cm.The test point at concrete edge is positioned at the scope from concrete surface 2cm in said temperature sensor and the concrete strain gauge.
Concrete temperature test: the thermometric time interval is not more than 2 hours once, but after 7 days the time interval can suitably increase.Test atmospheric temperature simultaneously; Record weather condition every day.
Strain testing: adopt Jinma High-Tech Industry Co., Ltd, Changsha to produce
The flush type concrete strain gauge, adopt simultaneously
The comprehensive logging of portable automaticAnd stuck-module, can be at the remote monitoring ess-strain.
Strain testing can adopt with temperature test synchronous, and the test point in concrete can be adjusted as required in temperature sensor and the concrete strain gauge.
