Technical Bulletins

Concrete Alberta provides a number of Technical Bulletins designed to provide overviews of key topics of interest specific to our industry in Alberta, they include:

TECHNICAL BULLETIN #1:

Alkali Aggregate Reactivity

Sampling and evaluation of Alberta aggregates conducted over the past several decades have indicated that the majority of aggregate sources in this province, are potentially reactive in the presence of an alkali source – namely the alkalies from cements and some supplementary cementing materials. The majority of local aggregate sources tested to date have shown to be at least moderately reactive. As resources are depleted and new ones developed, an increasing number have been found to be highly reactive...

TECHNICAL BULLETIN #2:

Coloured Concrete

In order to enhance the architectural features of concrete projects, designers can use colour. Concrete can be almost any colour desired beyond its standard grey. Pigments, shakes and stains are used to produce the range of colours. The colours can be used in conjunction with various textures including exposed aggregate, stamped and form liners...

TECHNICAL BULLETIN #3:

Curing Concrete

CSA A23.1 mandates some form of curing of all concrete under the standard, regardless of exposure class. CSA stipulates different types and periods of curing depending on the exposure class of the hardened finished product...

TECHNICAL BULLETIN #6:

Sulphate Resistant Concrete using Type HSe (Type HS Equivalent) Cement

“Kalicrete” (known today as Type HS cement) was developed and introduced to the Alberta market by the Canada Cement Company in 1930. It was purported to be the solution to placing concrete in high sulphate conditions. It has been employed very successfully for over 80 years. Today CSA A23.1 recognizes multiple approaches to providing durable cementing materials for long-lasting concrete for use in High Sulphate exposure conditions...

TECHNICAL BULLETIN #7:

Retempering Concrete

A number of circumstances can create challenges to the producer to deliver a consistent product from one load to the next and occasionally loads need to be adjusted on site before placement in the forms. Standards and codes often limit the extent to which a load can be adjusted on site. As such accurate measurement and assessment of the relevant parameters of a load are crucial before selecting and implementing any measure to adjust the load...

TECHNICAL BULLETIN #8:

Reducing Ready Mixed Concrete Temperatures in Hot Weather

In summer months, the producer is often presented with an additional performance requirement, concrete temperature, which they are challenged to meet by the impact of ambient temperatures on the materials used to make ready mixed concrete. Concrete temperature affects the performance outcomes. However, several provisions can be put in place by the producer to address these challenges...

TECHNICAL BULLETIN #9:

Points for Consideration in Creating a Comprehensive Quality Control Plan for Concrete Producers

Determine the scope and purpose of your QC Plan. Consider what personnel, actions or processes are most critical for maintaining quality of concrete for your organization - it is these elements which should be written into a QC Plan...
