Concrete Anchor Pull-Out Specimens (3 Blocks, Exploded)

Create a precise, true-to-scale 2D civil engineering cross-sectional detail drawing in millimeters (mm) showing three identical unreinforced concrete test blocks placed side-by-side horizontally with a 150 mm spacing between each block. 1. Concrete Block Geometry (Identical for all 3 blocks): - Width: 200 mm, Height: 250 mm (representing a 200 x 200 x 250 mm concrete block). - Apply standard ANSI concrete section hatching (AR-CONC) inside each block. - Label the top horizontal edge of each block as "SMOOTH FORMED FACE (PER ACI CODE-355.4-24 SEC. 4.5.1.2)". 2. Anchor Installation Details (Centered horizontally at X = 100 mm on the top face of each block): - Drill Hole Diameter: 14 mm (draw vertical hole walls 7 mm to the left and 7 mm to the right of the center axis). - Threaded Steel Rod Diameter: 12 mm (fischer M12 threaded rod, centered inside the 14 mm hole, leaving a 1 mm annular gap on each side for the adhesive resin layer). - Exposed Rod Protrusion: Extend the 12 mm threaded rod 50 mm vertically above the top concrete surface on all three specimens, showing external thread hatching. - Adhesive Resin Layer: Fill the 1 mm annular space and the bottom tip of the drilled hole with solid or dense stipple hatching to represent the fischer Resin Capsule RM II 12 adhesive matrix. 3. Varying Embedment Depths (Left to Right): - Specimen 1 (Left - Compliant Control): Drilled hole and embedded M12 rod depth (h_ef) = 110 mm below the top surface. Remaining bottom concrete cover = 140 mm. Title below block: "GROUP CC-110: COMPLIANT BASELINE (h_ef = 110 mm)". - Specimen 2 (Middle - Moderately Shallow): Drilled hole and embedded M12 rod depth (h_ef) = 80 mm below the top surface. Remaining bottom concrete cover = 170 mm. Title below block: "GROUP NC-80: SUB-COMPLIANT (h_ef = 80 mm)". - Specimen 3 (Right - Critically Shallow): Drilled hole and embedded M12 rod depth (h_ef) = 60 mm below the top surface. Remaining bottom concrete cover = 190 mm. Title below block: "GROUP NC-60: NON-COMPLIANT (h_ef = 60 mm)". 4. Dimensioning & Annotations: - Include clean, standard architectural/engineering dimension lines with arrows for the 200 mm block width, 250 mm block height, 50 mm rod protrusion, and the respective embedment depths (110 mm, 80 mm, and 60 mm) and bottom concrete covers (140 mm, 170 mm, and 190 mm). - Add leader callouts pointing to: "fischer M12 Threaded Steel Rod (RG M / FTR)", "Ø14 mm Drilled Hole", "fischer Resin Capsule RM II 12 Adhesive Layer", and "Unreinforced M25 Concrete Block (200 x 200 x 250 mm)". - Use clean black vector linework on a white background with standard engineering sans-serif text.
