The leading voice for the crushed stone, ready mixed concrete, sand and gravel, and cement industries' community.
PELA is a 10-month hybrid program with online and in-person educational sessions and networking opportunities.
Careers in the Aggregates, Concrete & Cement Industries
The Pennsylvania Aggregates and Concrete Association (PACA) is the industry’s unified voice, representing more than 200 member companies across the state.
Creating a unified and strong voice for our industry.
PACA monitors and analyzes local, state and federal regulations and advocates for a balanced approach by the regulators.
PACA builds a bridge between our members and our partners at PennDOT, and the Pennsylvania Turnpike Commission along with Pennsylvania’s construction industry to further the use of our materials to the benefit of the commonwealth.
One of the most effective tools in government relations for an industry is a robust advocacy/grassroots strategy.
In the last legislative session, we contributed over $275,000 to our political champions.
November 2025 at Hotel Hershey in Hershey, PA (PACA members only event).
PACA offers comprehensive concrete certification programs for ACI, NRMCA, and PennDOT in the central Pennsylvania area.
Membership has its privileges - most of PACA's events are open to PACA members only.
PACA conducts numerous education and training events during the year.
Choose concrete for your next parking lot project.
Streets built with concrete are built to last, consider concrete for your next project.
Concrete's strong, resilient and the choice for your next building or bridge.
PACA works with the National Ready Mixed Concrete Association (NRMCA) to convert your parking lot or building project to concrete without hurting your bottom line.
PACA drives a member-approved strategic plan to increase market share and engages specifiers and owners on the value of concrete in their projects.
This program provides free continuing education to the design and specifying communities. There are currently four courses available, ranging from 30 minutes to 60 minutes focused on the cement, aggregates and concrete industries. You'll receive a certificate of completion once you pass a quiz. The bookmarking feature allows you to leave the course and resume where you left off when you return.

Concrete is one of the most widely-used materials in the world; in fact, the US produces 350 million cubic yards of it annually to build roads, buildings, dams, etc. Additionally, the worldwide production of Portland cement (used to bind concrete together) is projected to increase to 4.4 billion metric tons by 2050. With increased demand and production, there is a growing concern about its rather large carbon footprint – producing this material is an energy-intensive process that emits enormous amounts of carbon dioxide (CO2) and a range of other pollutants.

Concrete’s durability is the main reason it is the most sought after building material. As such, most of the focus is on mixing the material to ensure maximum strength. However the next process, known as curing, may be more important. Concrete gets its strength through hydration. This reaction occurs due to the water in the concrete mix. To ensure that the concrete is reaches its maximum potential maintaining that moisture is critical. That is where curing starts.

American infrastructure has been deteriorating at a shocking pace. Just last year, the State of Pennsylvania received a low rating of ‘C-‘ in the infrastructure report card by the American Society of Civil Engineers. To address this problem, researchers have been testing different materials, and ways of enhancing the performance of concrete for decades. We are now finally close to developing the perfect replacement for ordinary concrete, i.e., Bendable Concrete.

Simply put, maturity is a real-time approach to estimating the compressive strength of in-place concrete, and relating it to the effects of temperature and time. This process is used to measure the progression of the curing process; it is an accurate indexing method of figuring out the strength of the concrete, while it cures. The maturity method, often just called maturity, carries out strength testing in a non-destructive manner, making it ideal for use by builders, suppliers, and subcontractors. It is the perfect way of conducting quick evaluations to determine the exact instant at which the concrete reaches its required strength. Since maturity is directly related to the strength and durability of the concrete, this method is the best way to measure it without depending on standard laboratory testing, or using test specimens. It can virtually eliminate the use of concrete cylinder break testing, with the exception of breaking cylinders as a means of verification.

Rising global economies and population have caused the construction industry to grow at a rapid pace. In turn, this has made cement as vital and valuable as oil, especially since this common building material is admirably versatile, and is widely used for constructing infrastructure, bridges, roads, etc. Consider this: the concrete market has experienced a steady growth in the US since 2011. The production of concrete amounted to about 98 million metric tons in 2017, with predictions of further increments. This expansion is largely fueled by the integration of technology into the concrete industry, leading to the development of special materials and advanced processes – designed to meet the growing need in an eco-friendly way.

Concrete is the most widely used building material in the world. However, researchers and manufacturers have been working together to produce different types of concrete to improve the overall quality and the economic value of construction. As a result, translucent concrete has gained popularity in many industries across the world. As an energy saving and eco-friendly building material, Light Transmitting or translucent concrete is now increasingly used in fine architecture and cladding for interiors. Here’s everything you need to know about translucent concrete and its future in the construction industry.

Concrete is a mixture of cement, gravel, sand, water and a range of aggregates. With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water. It is also the world’s most widely used material for construction – from bridges to large buildings, concrete forms the very foundation of our infrastructure. Over 70% of the world’s population lives in a concrete structure.

The process of curing concrete is an important step in providing sufficient hydration to the building material. This is achieved by employing specific methods to maintain a certain level of moisture, and prevent the fall of temperature brought about by heat loss. Curing concrete also allows it to reach its optimal strength. The longer that it is left to cure, the more durable it will be. Some of the popular techniques for curing concrete are as follows:

From high rise buildings to suburban homes, concrete is the number one building material of choice for architects and designers around the world. Although wood is a close substitute, concrete has numerous benefits that make it the better option for most construction projects. Here are some reasons why concrete trumps wood as a building material.

With origins dating back to ancient times, modern concrete and its main ingredient, i.e. cement, has been significantly modified over time. This remarkable material was used by the Romans and Greeks some 2,000 years ago – who used volcanic ash and lime, which, when mixed with water, formed a hard mass. It was finally in 1891, that the first concrete street was poured in the United States, in Ohio.
The program is delivered in one (1) module and it should take approximately 30 minutes to complete. You will receive a certificate of completion once you pass the quiz. The bookmarking feature will allow you to leave the course and resume where you left off when you return.
