Railway 2024 quotas: looking up base-period prices of sand — TB/T 10813-2024 sand table, medium-coarse sand by use, machine-made sand listed separately

Topic Positioning

How to look up, and the actual data of, sand base-period prices in the railway 2024 quotas: the table's location, computer codes, classification logic (medium-coarse sand by use, not fineness modulus), machine-made sand listed separately, price levels, and application essentials.

Core Conclusions

Source and lookup: TB/T 10813-2024 "Base-period prices of railway works materials", Chapter 2 "common materials" -> Section 8 "aggregate" -> "1. sand and mortar". General 1.0.2: the prices serve compiling quotas, estimates, and budgets; implementation-stage prices are market-determined; 1.0.3: prices are 2020-level and ex-deductible-VAT. In software, call by computer code (unified material codes; sands in the 1080xxx range).

The sand table (unit m3; Class A sand unit weight 1.430000 t/m3):

Code	Name and spec	Base price (yuan/m3)	Class
1080105	Fine sand	48.50	A
1080209	Medium-coarse sand (filling)	60.63	A
1080313	Medium-coarse sand (masonry)	65.48	A
1080417	Medium-coarse sand (beams)	72.02	A
1080521	Medium-coarse sand (track slabs)	73.46	A
1080625	Machine-made sand	65.50	A
1080729	Refined sand (for CA mortar)	53.10	A
1081249	Green-bean sand	52.82	C

Also in the table: barite sand 0.57 yuan/kg, dolomite sand 1.26, black-carbon emery 7.28, quartz sand 0.38, epoxy colored sand (regular colors) 4.00 (all Class C); dry-mixed masonry mortars M5.0 476.93 yuan/m3, M7.5 483.55 (Class C).

Classification logic: the railway material library does not split "medium/coarse" by fineness modulus — one "medium-coarse sand" by use in four bands (filling / masonry / beams / track slabs), machine-made sand listed separately, plus fine and refined sands.

Price level: fine about 48.5 -> filling 60.6 -> masonry/machine-made about 65.5 -> beams 72 -> track slabs 73.5 yuan/m3, overall 48-74. Machine-made (65.50) is nearly level with masonry medium-coarse (65.48), about 8% above filling, about 10% below beams/track slabs.

Composition caliber: sand is Class A; per general 1.0.4 item 1, Class A base price = original price x (1 + procurement and custody rate); the rate per TB 10811-2024 Table 2.2.2 — sand 4.47% (cement 3.78%, crushed stone 3.45%, brick/tile/lime 4.98%, others 2.65%). Class A excludes freight; freight-outside-price to a delivery point is computed separately in the item estimate (budget).

Application essentials: match the sand to the quota item — different parts (masonry/beams/track slabs/filling) cite different codes of medium-coarse sand; do not mix. Machine-made sand appears in machine-made-sand concrete or items marked "machine-made sand" — check the code attached to the item's consumption table before pricing.

Applicable Boundaries

For looking up sand base-period prices when compiling railway quotas, estimates, and budgets (general 1.0.2). Base prices are 2020-level, ex-deductible-VAT; compilation-period prices are survey prices ex-deductible-VAT, determined by the designer (TB 10811-2024 Clause 2.2.3), with differences booked as price differences. Implementation-stage prices are market-determined. Figures are the uniform national base, not regional compilation-period prices; water (0.55 yuan/t) and power (0.47 yuan/kWh) bases are in TB 10811-2024 Clauses 2.2.4/2.2.5 — outside this card.
