the air emissions from gravel processing consists of heavy particles that may settle out within the plant area. (fine aggregate), and coarse aggregate, consisting of crushed stone. Sand, aggregate, cement, and water are all gravity fed from a weigh hopper into the mixer trucks. The cement is transferred to elevated storage silos. The sand

A cradle to gate LCA framework for emissions and energy

Jun 01, 2016 The crushed stone and the gravel and sand industries do not specifically align with the coarse and fine aggregate materials used in conventional concrete, therefore a singular aggregate emission factor was created to better represent the total amount of emitted CO 2 eq emissions from the aggregate fraction of concrete.

DRILLING & BLASTING OPERATIONS

drilling PM10 emission factor is based on information published in Section 11.19.2 of AP-42 (1/95) for crushed stone processing operations. The blasting procedure is based on an emission estimation technique provided in Section 11.9.2 of AP-42 (Reformatted 1/95) for coal or overburden. A PM10 fraction of 52% is assumed for blasting emissions.

Environmental impact of concrete

The CO 2 emission from the concrete production is directly proportional to the cement content used in the concrete mix; 900 kg of CO 2 are emitted for the fabrication of every ton of cement, accounting for 88% of the emissions associated with the average concrete mix.
