It closes, various cement mortar material is made；The mass ratio of cement, river sand and water is 0.8 ~ 1.2:1.8 ~ 2.2:0.30 ~ 0.40；
(2) various cement mortar material is vertically uniformly poured into multilayer in a mold, is put into 45 DEG C of 35 DEG C of ~
Warm and humid curing box demoulds after ~ 60 hours 40 hours；
(3) it under 18 DEG C 25 DEG C of ~ of constant temperature, conserves ~ 35 days 25 days and forms.
The cement mortar that the present invention is mixed to form using ordinary cement, river sand and water pours into multilayer, the model of formation with
Stratiform opposite sex rock mass is similar, reduces the acquisition difficulty of stratiform opposite sex rock mass and the procurement cost of stratiform opposite sex rock mass.This hair
Bright cement grade can be selected arbitrarily, the number of plies can be multilayer and cement layer handled by position can change, make final mould
Type matches with a variety of stratiform opposite sex rock mass.Its production of stratiform cement mortar material made of the present invention is simple, adult is cheap, and
And good forming effect, the international standard cylinder sample being cut into carry out triaxial test, can effectively obtain the deformation of different structure
Rule discloses non-compatible deformation feature and affecting laws.
Further, in above-mentioned steps (1), cement, river sand, the mass ratio of water is 1:2:0.35.
Further, in above-mentioned steps (2), the temperature in warm and humid curing box is 38 DEG C, is placed in warm and humid curing box
Time is 48 hours；In step (3), curing time is 28 days.
Further, in above-mentioned steps (1), cement type has 5 kinds, and label is respectively 325,425,525,625,725,
325 cement, 425 cement, 525 cement, 625 cement, 725 cement are sequentially overlapped from top to bottom, form 5 layers；The diameter grain of river sand is small
In 2mm.
The index marked as cement " intensity " of cement of the present invention.The intensity of cement is to indicate unit area stress
Size, the solid degree after referring to that cement plus water mixes and stirs, after being condensed, being hardened.The intensity of cement is determining cement grade
Index, and select the main foundation of cement.
Stratiform opposite sex Similar Material of Rockmass is prepared using the above method.
The invention has the following advantages:
The present invention is made stratiform opposite sex Similar Material of Rockmass using ordinary cement, river sand and water proportion and makes simple, cost
It is cheap, and good forming effect, meet the experiment needs of various beded rock mass, reduces the acquisition difficulty and acquisition of beded rock mass
Cost.
