Description
Technical field
The utility model relates to a kind of concrete analyzer, more specifically is a kind of concrete alkali analyzer, dependent territory worker's test apparatus technical field.
Background technology
Alkali mainly is owing to the higher [w (R of alkali content in the cement
20)〉O.6%], contains active Si0 in gathering materials simultaneously
2The time, alkali will with gather materials in active Si02 reaction, form the alkaline silicate gel.Though cement belongs to alkaline matter, generally can resist the erosion of bases, but alkali content is higher in cement paste structure, and when containing active substance in the gathering materials of concrete batching, water mudrock structure is through obvious swelling cracking occurring behind the certain hour, even peel off the breakoff phenomenons such as defeated and dispersed, be called alkali.Because the fast development of modern industry for enlarging the concrete aggregate source, takes full advantage of industrial residue, when containing the alkali additive and being widely used in producing, improve concrete quality, the research of alkali is also become to become more and more important.
The alkaline silicate gel that alkali generates has great water absorbing properties, in gathering the process of moisture, produce and expand, for this reason, it is by at a certain temperature that concrete alkali is measured, the change in size of wet environment concrete sample obtains, the alkali analyzer of existing concrete comprises specimen mounting, dial gauge and dial framework, when alkali is measured, concrete sample is placed on the specimen mounting, dial gauge is fixed on the dial framework, and the measuring point of dial gauge is just in time at the top of concrete sample, according to the variable quantity of the length of concrete sample in time, namely then the variable quantity of the reading of dial gauge calculates alkali.Said apparatus needs to carry out under constant temperature, for keeping the temperature constant of whole test environment, needs the larger energy of consumption rate; Simultaneously test need to be carried out under the environment of high humidity, therefore, also needs whole test environment is regularly sprayed water, and both waste water resource made again the alkali measurement operation complicated.
The utility model content
For above-mentioned situation, the problem that the utility model quasi-solution is determined provides that a kind of energy and water resources consumption are economized, easy to operate concrete alkali analyzer.
For addressing the above problem, the utility model has adopted following technical scheme: a kind of concrete alkali analyzer, comprise several length measurment table and dial frameworks, described length measurment table comprises table body and measuring staff, it also comprises temperature control equipment, constant temperature oven and several buckets, described temperature control equipment comprises compressor and heat exchanger, described heat exchanger is in constant temperature oven, described several buckets are in constant temperature oven, the quantity of described bucket equates with the quantity of length measurment table, described dial framework is arranged on the top of constant temperature oven, described several length measurment tables are separately fixed on the dial framework, and the measuring staff of described several length measurment tables penetrates respectively constant temperature oven, and point to respectively several buckets; When concrete alkali analyzer used, described bucket was marked with water, and concrete sample is immersed in the interior water of bucket, and the measuring staff of described length measurment table is at the top of concrete sample.
Described length measurment table is dial gauge or clock gauge.
As preferably, above-mentioned concrete alkali analyzer, it also comprises control device, described control device is connected with length measurment table, thermostat signals.
Adopt said structure, concrete alkali analyzer of the present utility model, on the one hand, owing to be provided with constant temperature oven and temperature control equipment, guaranteed that concrete alkali carries out in the isoperibol of constant temperature oven, avoid prior art need to keep the temperature constant of whole test environment, saved the energy.On the other hand; in constant temperature oven, be provided with several buckets; when concrete alkali; bucket is marked with water; concrete sample is immersed in the interior water of bucket, can guarantee that so concrete alkali carries out in the environment of high humidity, has avoided prior art that whole test environment is regularly sprayed water; saving water resource makes again the alkali measurement operation simple.Again on the one hand, because concrete alkali analyzer of the present utility model is provided with several length measurment tables and several buckets, can carry out simultaneously alkali to several concrete samples and measure, improve the work efficiency of concrete alkali analyzer.
