Description
Technical field
The invention belongs to civil engineering material research and applied technical fields, and in particular to a kind of to be measured using sand fineness
The analysis method of sand quality.
Background technique
It is well known that concrete is essential material in civil construction project, and the fineness of sand matching in concrete
It is occupied an important position again in composition and division in a proportion design, if the fineness of sand changes, sand coarse aggregate ratio and amount of water will also be subject to accordingly
Adjustment, could maintain the workability of concrete constant.The fineness modulus of sand is characterization natural sand and Machine-made Sand partial size fineness
With the index of classification, although it cannot the gradation of reaction particles completely still can be certain as a kind of concise index
Sand qualitative difference is reacted in degree, so in engineer application and concrete test, most of engineers and technicians and its
Related scientific research personnel evaluate the fineness of sand with the fineness modulus of sand.
Summary of the invention
The object of the present invention is to provide a kind of easy to operate, high-efficient analyses using sand fineness measurement sand quality
Method.
A kind of analysis method using sand fineness measurement sand quality, including following technique,
(1) sand is dried, obtains baked sand；

26%.It is the key that control mortar fluidity through the sand that 0.15mm is obtained by filtration.
Further, the baked sand is natural sand or Machine-made Sand.What natural sand was formed by natural conditions effect, pass through
Shui Chong, river are washed to be formed, and have round and smooth shape, and quality is hard；Machine-made Sand refers to through sand making machine and the processing of other auxiliary devices
Made of sand, finished product is more regular, can be required be processed into the sand of Different Rule and size according to different process, can more expired
Sufficient daily demand.
Further, natural sand successively via hole diameter be 2.36mm, 1.18mm, 0.63mm, 0.315mm and 0.15mm sieve
Remaining powder accounts for the 0-5% of baked sand total amount after filtering；Machine-made Sand successively via hole diameter be 2.36mm, 1.18mm, 0.63mm,
Remaining powder accounts for the 0-15% of Machine-made Sand sand total amount after the screen filtration of 0.315mm and 0.15mm；Machine-made Sand particle is sharp, more
Corner angle, rough surface, compared with natural sand, the grain composition of Machine-made Sand is slightly worse, and the powder for causing Machine-made Sand remaining is than natural
Sand is more.
Beneficial effects of the present invention are：A kind of analysis method using sand fineness measurement sand quality of the present invention,
It operates fairly simple, sand can carry out to reasonable grain composition, the sand of reasonable grain composition can make ingredient obtain low gas
Porosity improves the quality of product, solves the problems, such as that hollowing occurs to ingredient in mortar in use.In use, people
The sand of variable grain gradation is added as needed, it is corresponding to solve the problems, such as, improve the construction quality of engineering, save
Construction cost.
