R Collard Ltd is constantly evolving and innovating to bring you, the customer more products and services in a sustainable and competitive way.

R Collard Ltd would like to introduce our range of ready mixed concretes for our existing and new customers.

The range is split into two offerings: -

BSI Quality Assured concrete production BS EN 206:2013 + A1:2016 and BS 8500

High quality concrete produced in line with the British Standard more suited to higher strength and design mixes, where the specifier needs to meet particular standards such as NHBC.

Non Quality Assured concrete production

Concrete which is produced in exactly the same way as the quality assured concrete, but higher percentages of recycled products are introduced to the mixes. This option is a more sustainable option for footings, kerbing and nominal mixes where strength guarantees are less of a priority. This option is also more economical and very competitive.

BSI quality assured products are produced in line with the British Standard specification whereby the production of aggregates, sands and cements are all part of the assessment as well as the actual production process itself. Our new state of the art concrete batching plant is designed and built in Ireland by McCrory Engineering.

Efficient and award-winning logistics

Concrete can be ordered and delivered the same day our award winning logistic uses various vehicles for deliveries mixer trucks (4m3, 6m3 & 8m3) and various size tipper trucks for dry lean.

Our ready-mixed concrete plant is set up to produce many types of concrete. The concrete mixes have been designed to meet the potential specifications of our clients. The constituent materials are batched by weight and not volume. This means that the concrete batched will be as originally designed and comply to the rigorous quality control systems implemented.

There are 5 main categories which have been devised to assist in the ordering of the concrete dependent on the needs and technical awareness of the customer. Although concrete can be ordered by discussion and arrangement with us here at R Collard Ltd. The British Standard BS 8500-1 Concrete - Complementary British Standard to BS EN 206 (in 2 parts) has been used by industry from December 2003 (replacing BS 5328). Using this standard, concrete shall be specified either as;

Designated concrete
Designed concrete
Prescribed concrete
Standardised prescribed concretes
or Proprietary concrete

all conforming to part 2 of BS 8500 and BS EN 206 Concrete, Specification, performance, production and conformity.

BS 8500 was revised and republished in 2015 to reflect that BS EN 206-1 (2000) and BS EN 206-9 (2010) Concrete: Additional rules for self-compacting concrete have been revised and rationalised as a single Standard BS EN 206:2013.

 

Record keeping and monitoring

Our concrete batching plant is completely automated, allowing all data and batch records to be recorded. This automatic information comes from computerised systems with input from load cells on materials weigh scales, flow meters on water and admixture dispensers, moisture contents from meters fitted to the aggregate bins and concrete mixer.

Our batch records comprise the following:
- information related to the identification of the load
- size of the load in cubic metres
- theoretical quantities of constituents to be batched, (which are the mix proportions
for a cubic metre multiplied by the load size)
- moisture contents of the aggregates
- required quantities of constituents to be batched, (which are the theoretical quantities
after adjustment for the moisture content of the aggregates)
- the actual quantities batched
- the difference between the required quantity and the actual quantity. (This information
may be used to confirm that the batching tolerances have been achieved. It is rare
that the exact required quantities are batched and this is why standards permit
small batching tolerances)
- the effective or total w/c ratio for the load
