Description
Technical field
The utility model relates to a kind of devices that concrete sample is matched, and belong to concrete curing construction test technology
Field.
Background technique
With the quickening of Process of Urbanization Construction process paces, the rapid development of building trade, according to " Architectural Structure Design term
With symbol standard " regulation of GB/T50083-97, the definition of strength grade of concrete is: according to compressive strength of concrete
The intensity rank that standard value divides.Characteristic value of cubic concrete compressive strength means the side according to standard method production maintenance
The cube specimen of a length of 150mm, in the compression strength with 95% fraction that 28d age is measured with standard test method.
Strength grade of concrete is the strength grade of concrete symbol C and cube divided according to cube resistance to compression normal intensity
Compressive strength standard value (in terms of MPa) indicates that normal concrete divides are as follows: C7.5, C10, C15, C20, C25, C30, C35,
12 grades such as C40, C45, C50, C55, C60.
Performance: the relative density of portland cement is 3.1~3.2.Cement is contacted with water can release heat, by a timing
Between just condense (cement of different cultivars has different setting times).To guarantee that cement has suitable setting time, it is commonly incorporated into suitable
The gypsum of amount, chemical fertilizer industry byproduct ardealite, fluorgypsum also limited standard.It is ripe that the additional amount of gypsum depends mainly on cement
The content of aluminate in material, additional amount is with sulfur trioxide no more than 3.5%.Cement should have good volume stability.It is solidifying
Cement after knot is consolidated and with hard quickly in water with mechanical strength (resistance to compression and flexural strength) in air.Generally with cement: sand
The mortar specimen of=1:2.5 conserves 3 days, 7 days and 28 days resistance to compressions and flexural strengths in water, meets national standard as water
The intensity index of mud in terms of kg/cm2, and is known as with the numerical value of 28 days compression strength the label of cement.Portland cement is common
Label has 325,425,525 and 625.Some high-strength and Ultrastrength cement label, even up to 1000 or more.In clinker
Hydration reaction (being hydrated) occurs when each mineral and water contact, while generating calcium hydroxide, hydrated calcium silicate gel, aquation aluminic acid
Calcium and hydrated calcium ferrite etc..When there is gypsum, latter two hyrate generates hydrated calcium aluminate sulfate and aquation sulphur calcium ferrite respectively.Water
Slurry body can be shunk in dry conditions, can be expanded in wet condition.Calcium hydroxide and drated calcium aluminate will be by sulphur in seawater
The corrosion function of hydrochlorate, therefore the content of calcium aluminate in cement is limited cement used in harbour etc..If alkali content mistake in cement
Height, and when gathering materials containing active silica of concrete is made, it also occur that alkali-aggregate reaction, volume expansion, Behavior of Hardened Cement Paste
It will be damaged with concrete.Excessive free calcium oxide and periclase also generate volume expansion in hydration reaction in clinker, make
Bad at cement volume stability, this cement is with regard to unqualified.
Therefore, designing a kind of mold and carrying out test to concrete sample is highly desirable.
