Autoclaved aerated concrete blocks are mixed, cast, cut and steam-cured in a tightly timed process. A small error in timing or handling affects a whole batch. This page covers the people side of AAC plants.
Not sure what you need? Tell us about your business in six short steps and we will come to the first meeting prepared.
Share your requirementsAn AAC plant mixes fly ash or sand, cement, lime, gypsum and aluminium powder into a slurry, pours it into moulds and lets it rise. After setting, a cutting line slices the cake into blocks with wires, and the blocks are loaded into an autoclave for steam curing under high pressure. Only then are they packed and loaded on trucks. A small group of operators controls batching, cutting and the autoclave, and most others handle blocks, pallets and trucks. The process is timed, so a missed step wastes a batch. Autoclaves are pressure vessels and need trained, authorised attendants. Dispatch is heavy and truck-driven, and customers include builders with urgent sites. See also HR for manufacturing.
These are the places the people side of this kind of business tends to give way. The rest of this page works through them.
HR here has to work for each of these groups, not only the office. The set-up below is written with all of them in mind.
GullyHR runs talent acquisition for permanent roles in AAC block manufacturers. For each role we agree the job description with you, find and screen candidates against it, and support the offer through to joining. Tell us the role and the number of people, and we start there.
We recruit permanent employees. We do not supply contract or temporary staff.
Every business interviews, but few have a written process that works the same way for every role and every interviewer. GullyHR designs yours, from the role brief to the offer, trains your managers to run it, and can run it for you on the roles you hand us.
We agree what the role must deliver, the must-have and nice-to-have skills, and how each will be scored.
Screening call, assessment, interview rounds and decision points, sized to the role and the number of people you hire.
Structured questions for each role family and a rating guide, so two interviewers judge the same answer the same way.
A short briefing for your managers on what to ask, what to avoid and how to give a clear yes or no.
Who approves, how the offer is made, and how candidates are kept informed from first call to joining.
A late pour, missed rise time or early cut ruins a batch. Absenteeism or slow handover at the mixing stage hits everything downstream.
Pressure, temperature and cycle timing must be watched closely by authorised, rested people. Cover for absence is thin.
A new cutter wastes blocks and wires. The best operator holds the knowledge, and training is by watching.
Green and cured blocks chip at moving, stacking and loading. Blame falls on loaders who were never shown the method.
Trucks arrive in bunches and builders push for early dispatch. Loaders work fast and injuries and damage follow.
Cement, lime and fly ash irritate skin and lungs. Masks, gloves and washing facilities are used unevenly.
A strength or density test may delay dispatch, and lab staff feel pressure to pass the batch.
Plants sit away from towns, so travel, housing and migrant crews affect attendance and retention.
Start with the topics that matter most here: Health, Safety and Wellbeing; HR Strategy and Workforce Planning; Learning and Development. Then work through the rest. Each topic is written for manufacturing, not in general.
Induction, records, incident reporting and follow-through.

Named backups for the roles that cannot be vacant.

Who leaves, when, why — and which of them mattered.
Resignation to relieving letter, in a defined order.
Records that survive people, and approvals that do not queue.

Mixing, cutting and autoclave staff, since a mistake at those stages affects a full batch. Plan named cover for each, and train backups on real shifts.
Teach a handling method, use suitable pallets and straps and record breakage by shift and loader. Review without blame first.
Authorisation, training, duty hours, rest and handover notes. Ask a qualified professional what applies to your equipment.
Write the rule that a failed test holds the batch, back it from the top and keep dispatch out of the lab's decisions.
Look at travel, housing, pay timing and shift patterns. Hire locally, arrange transport where useful and talk to leavers about what changed their mind.
We would ask who covers each timed step, how autoclave staff are authorised and how breakage is traced. A good opening project is a station-and-cover chart plus an authorisation list. Scope is then written down for you to accept or change.
