EboraBot Materials & Testing Solver
Sieve analysis & fineness modulus, specific gravity & absorption, concrete mix proportioning and strength tests, steel tension tests, timber moisture, and the Marshall asphalt method — solved step by step, the way your prof wants them written.
Step-by-step solutions for Construction Materials and Testing — sieve analysis and fineness modulus, gradation and effective size, specific gravity and absorption of aggregates, moisture content and batch-water corrections, unit weight and voids; Portland cement properties; fresh-concrete water–cement ratio, slump, yield and absolute-volume mix proportioning; hardened-concrete compressive, splitting-tensile and flexural (modulus-of-rupture) strength and the statistics of test results; steel-bar tension tests (yield, ultimate, % elongation); timber moisture content and strength; and bituminous Marshall mix design (stability, flow, air voids, VMA, VFA). Now with Text+Figure mode — upload a photo of a problem that includes a sieve-analysis table, a gradation curve, a specimen sketch, a Marshall data set, or a stress–strain plot, and EboraBot reads both the text and the figure.
Use this for problems whose photo includes a figure — a free-body diagram, beam diagram, shaft, cross-section, table of material properties, or any visual the problem text references. EboraBot reads both the text and the figure, then solves step-by-step. Costs 15 EP per problem (~2× a regular scan, because the vision step is heavier).

⚠️ Multiple problems detected
It looks like you've sent several separate problems in one request.
This app is priced per problem — only 2 EP each — and works best when students send one problem at a time. If you continue, EboraBot will only solve the first one and explain why, but you'll still be charged 2 EP.
💡 Tip: send each problem separately for the same 2 EP cost. You'll also remember each solution better when you study them one at a time.
Before you scan
EboraBot reads the problem text from your photo, then sends it to the solver. Heads up:
- It can misread numbers — a "5" might become "3", units can flip.
- It can miss givens hidden in figures or in a footnote.
- Always check the extracted text before solving — you can edit it.
- The solution is a first draft. Verify against your notes and what your professor taught.
About Text+Figure mode
Text+Figure mode reads both the problem text and the figure (FBD, beam diagram, cross-section, table, etc.) in your photo, then solves step-by-step. Heads up:
- Costs 15 EP per problem (~2× a text-only scan).
- Use only when there's a figure you need to interpret. For pure word problems, the regular Scan tab is cheaper.
- Take a straight, clear photo — angled or blurry diagrams confuse the figure reader.
- Always check the extracted figure summary before trusting the solution.
