Description
Technical field
The present invention relates to a kind of construction material, specifically a kind of high-intensity concrete.
Background technology
Concrete is referred to as concrete: refer to by the gelling material cementing general designation that becomes whole engineered composite material of will gathering materials.Usually concrete one word of saying refers to make gelling material with cement, and sand, masonry gather materials; Cooperate by a certain percentage with water (adding or do not add admixture and adulterant), through stirring, moulding, maintenance and cement concrete, also claim normal concrete, it is widely used in civil engineering work.Briefly make the whether good concrete core key of a pile and be cement and aggregate.
The intensity of cement is distinguished by grade usually: according to the regulation of GB175-2007 " general purpose portland cement ", adopt the method for GB/T17671-1999 " Test method for strength of hydraulic cement mortar (ISO method) " regulation, with cement, standard sand and water were in 1: 3.0: 0.5 ratio, make the standard specimen of 40mm * 40mm * 160mm, under the normal curing condition, (in the 1d be 20 ± 1 degrees centigrade, relative humidity is in the air more than 90%, being in 20 ± 1 degrees centigrade the water behind the 1d) maintenance is to length of time of regulation, and in accordance with regulations method is measured folding strength and the ultimate compression strength of its 3d and 28d respectively.Divide the strength of cement grade according to the result who measures.As silicate cement (P. I/P. II) be divided into 42.5,42.5R, 52.5,52.5R, 62.5 and six strength grades of 62.5R (minimum value that represents respectively the compressive strength standard value of test specimen 28d is 42.5MPa, 52.5MPa, 62.5MPa, and with R is the early-strength type grade).
Aggregate: the granular loose material that namely in concrete, plays skeleton or filling effect.Divide coarse aggregate and fine aggregate.Coarse aggregate comprises cobble, rubble, waste residue etc., and fine aggregate comprises middle fine sand, flyash etc.Particle diameter is called coarse aggregate greater than the aggregate of 4.75 mm, is commonly called as stone.Commonly used have two kinds on rubble and a cobble.Rubble is that natural rock or rock are made through Mechanical Crushing, screening, and particle diameter is greater than the rock particles of 4.75 mm.Cobble by weathering, potamic transport and sorting, accumulation form, particle diameter is greater than the rock particles of 4.75 mm.The length of cobble and gravel particle is elongated piece greater than 2.4 times of persons of median size of corresponding grade under this particle; Thickness is platy shaped particle (median size refers to the mean value of this grade superior and inferior limit of particle size) less than 0.4 times of person of median size.Cobble for building, rubble should satisfy the technical requirements of standard GB/T/T 14685-2001 " cobble for building, rubble ".The following aggregate of particle diameter 4.75 mm is called fine aggregate, is commonly called as sand.Sand is divided into natural sand, artificial sand two classes by the product source.Natural sand by weathering, potamic transport and sorting, accumulation form, particle diameter is less than the rock particles of 4.75 mm, but do not comprise the particle of soft rock, weathered rock.Natural sand comprises river sand, lake sand, mountain sand and desalted sea sand.Artificial sand is the Machine-made Sand through processing except soil, the general designation of mixed sand.
From the in nature differentiation that forms, cement belongs to the product after the artificial mechanism processing, aggregate generally be self-assembling formation or after the day after tomorrow Mechanical Crushing gained, therefore shape and the purity of aggregate all differ usually, if when containing hazardous substance above certain standard in the aggregate, will greatly reduce the actual strength behind the concrete coagulation.
